declarativeNetRequest addOrReplaceParams adds a parameter when already present
I'm trying to use DNR to force safe search with Qwant search engine. Under certain circumstances (scenario described below) the search is performed with an API which contains the safe search level in a URL parameter. A typical query URL is https://api.qwant.com/v3/search/web?q=test&count=10&locale=fr_FR&offset=0&device=desktop&tgp=1&safesearch=0&displayed=true&llm=true. I want a DNR rule to force safesearch to be 2 (= strict) (from some javascript code) : { id: 1, priority: 1, action: { type: 'redirect', "redirect": { "transform": { "queryTransform": { "addOrReplaceParams": [{ "key": "safesearch", "value": "2" }] } } } }, condition: { "urlFilter": "api.qwant.com/v3/search", "resourceTypes": ["xmlhttprequest"] }, } When this rule is activated, I end up with a URL with the original safesearch parameter AND the forced one : https://api.qwant.com/v3/search/web?q=test&count=10&locale=fr_FR&offset=0&device=desktop&tgp=1&safesearch=0&displayed=true&llm=true&safesearch=2. To reproduce this request (with the previous DNR rule in place) : navigate to https://www.qwant.com search for some string (test in my case). This displays the list of results ; click the engine button at the top right to display the settings pane ; inspect network request performed by this page ; change the Adult filter in the list -> the results are automatically updated with the new settings. The web request shows URL with the 2 safesearch parameters. I already used addOrReplaceParams in 'standard' contexts (main_frame) and it works just fine. Any hint on what goes on ? Thank you.

Incorrect page zoom after pinch-to-zoom and orientation change on Bing search page
Steps to Reproduce: Open the Bing search page in Safari (example URL: https://www.bing.com/search?q=webkit&form=APIPH1&PC=APPL). Pinch-zoom in or out, then return the page to exactly 100% zoom. Rotate the device from portrait to landscape orientation. Observe that the page is incorrectly scaled to a value other than 100%. Rotate the device back to portrait orientation. The page remains at the incorrect zoom level. Expected Result: After returning the page to 100% zoom, changing orientation should keep the zoom level at exactly 100% in both portrait and landscape modes. Actual Result: After returning to 100% zoom, rotating to landscape changes the zoom to a non-100% value, and rotating back to portrait retains the incorrect zoom level.

-webkit-touch-callout: none; not working in Safari on iOS 26.1
Hi everyone, I want users not to see the system context menu when long-pressing text on a page in Safari on iOS. I found on MDN that the CSS property -webkit-touch-callout: none; can achieve this. But in reality, it doesn't really work. MDN documents URL: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/-webkit-touch-callout Here’s a minimal example: function preventIOSSafariContextMenu() { if (document.getElementById(STYLE_ELEMENT_ID)) return; if (!IS_TOUCH_DEVICE) return; const style = document.createElement("style"); style.id = STYLE_ELEMENT_ID; style.textContent = ` html, body { -webkit-touch-callout: none !important; } `; (document.head || document.documentElement).appendChild(style); } The context menu persists. Has anyone else encountered this? Is this an intentional change in WebKit, or could it be a regression? If it’s intentional, is there a recommended alternative? Thanks in advance for any insights!

Guideline 3.2.2 Rejection - Correct Implementation for Donations via SFSafariViewController
Hello everyone, We've had our app rejected twice under Guideline 3.2.2 regarding charitable donations, and we're seeking clarification on the correct implementation. We've read the guidelines but want to confirm the technical approach with the community's experience. The Rejection Reason: Apple states: "We still noticed that your app includes the ability to collect charitable donations within the app..." They specify that since we are not an approved nonprofit, we must use one of the alternatives, primarily: "provide a link to your website that launches the default browser or SFSafariViewController for users to make a donation." Our Current (Rejected) Implementation: User taps a "Help" button in our native app. A native modal appears inside our app where the user enters their donation amount and email address for the receipt. The user clicks "Donate," which then opens an SFSafariViewController to our website's payment page (e.g., Stripe, PayPal). The amount and email are passed as URL parameters to pre-fill the form. Our Questions for the Community: Is the issue solely the fact that we have a native modal for data entry? We understand we cannot process the payment in-app, but we thought collecting the intent (amount, email) was acceptable before handing off to Safari. What is the definitive, compliant flow? Option A: Should the "Help" button do nothing more than open an SFSafariViewController to a generic donations landing page on our website (https://ourwebsite.com/donate), with no data pre-filled? The user must then navigate and enter all information on the website itself. Option C: The rejection also mentions SMS. Has anyone had success implementing a "Text-to-Donate" link instead of a web flow? Wording: The button in our app currently says "Donate". Should this be changed to a more passive call to action like "Visit Website to Donate" to make it absolutely clear the transaction is external? We want to ensure our next submission is successful. Any insight, especially from developers who have successfully navigated this exact rejection, would be immensely helpful. Thank you.

Notify web extension native process of user default changes
My Mac app and its Safari web extension share an app group, and I want to notify the web extension native process when the app makes a change to the app group NSUserDefaults, but I can't find a good way to do this. According to the documentation, "You can use key-value observing to register observers for specific keys of interest in order to be notified of all updates, regardless of whether changes are made within or outside the current process." In my testing, however, this doesn't work in the web extension process. I'm using NSUserDefaults addObserver forKeyPath, but observeValueForKeyPath never gets called. I've also tried NSDistributedNotificationCenter, but the web extension process doesn't receive the notifications sent by the main app. Are either of these supposed to work? If not, are there any alternatives?

Handling input type=date on iOS
I created a form field using: On Safari and Chrome desktop, it behaves as expected. Safari shows the current date in grey by default, and Chrome displays a format hint like dd.mm.yyyy, which is perfectly fine. On iOS, however, the field appears completely blank. I understand that the placeholder attribute is not part of the iOS date input behavior, which is technically fine. Still, it would be helpful if developers had the option to define a default display value. In the past, browsers prefilled date inputs, but many developers objected because they needed the field to be empty by default. I have searched extensively and tried several AI tools, and everywhere it says that this cannot be changed. Am I missing something, or is there any way to display a placeholder, the current date, or some kind of visual hint in iOS Safari? Right now, the empty field creates poor UX because users may overlook it. Since the field is required, this can easily lead to validation errors and additional friction. As a workaround, I used a CSS hack with input[type="date"]::before and a content attribute. I also added JavaScript to toggle a pseudo-placeholder value specifically for iOS. Is there a cleaner solution that avoids this workaround? Thanks in advance for your guidance.

First installation of the extension - sending messages to the background script from the event handler in the content script does not work
After the first installation (out of AppStore) of the extension in the browser, the content script is correctly inserted into the page (twice for some reason) and a message is sent from the root of the content script to the background script, which responds correctly. However, if an event handler is registered within the content script, within which the message is also sent to the background script, it will never reach the background script. window.addEventListener("message", function (event) { // We only accept messages from ourselves if (event.source !== window) { return; } if (event.data.source && event.data.source === appIdentification) { browser.runtime.sendMessage(event.data); } }, false); It does not matter with what delay the event handler is called (i.e. the background script is not asleep). If I refresh the page or close and reopen the browser and reload the page, everything works correctly and the message sent from the event handler is already delivered to the background script. The event handler is used so that the extension code is uniform for all browsers (Chrome, Safari, Edge, Opera, Firefox), i.e. it is not intended to use externally_connectable for sending messages from the webpage directly to the background script, which Safari should support. The expected behavior is that the extension will work even after the first installation, as is the case with other browsers. Procedure: Enter the test website: https://www.mssf.cz/testapp/check_client.aspx Do the initial installation of the extension (could be downloaded from here: https://1drv.ms/f/c/76f4c93826df41a0/Ej5MQX9ctyhHv_P9_t_6uAwB05ET-nzXuMhPeu56nOgkWg?e=cudqRJ) Set a breakpoint in the event handler for "message" within the content script, open the background script and set a breakpoint in the event handler for onMessage Click on the "Validate certificate" button on the page loaded in point 1 Step through the content script to the point where the message is sent to the background script, the breakpoint within the background script is never hit, which is an error, the message should come to the background script

WebXR Consent Dialog
Based on the "Build immersive web experiences with WebXR"-Video for visionOS there is no way to disable the consent prompts for entering an immersive experience or consent hand-tracking. For the microphone it's possible to "greenlight" specific websites for mic input, which works great. I'd welcome it, if it were possible to add specific websites in the settings, in which those consent dialogs aren't shown each time. In my opinion, the user interaction through a button that launches the experience would be sufficient to not disorient.

Extension in Safari Fails Auth in Non-Default Profile When Using Cookie-Based Mechanism
Hello, We are developing a Safari Web Extension that uses a cookie-based authentication mechanism. The extension makes a request to an endpoint e.g. /login, and this endpoint expects a cookie (e.g., sessionId) to be included with the request. Everything works correctly when running in the default Safari profile. However, when I install and run the same extension in a new, non-default profile, the behaviour changes: The request to /login is still made The cookie sent is not as expected As a result, the response returns null user data I confirmed that logging into the site in the new profile (in a tab) works, but the extension does not appear to share the session/cookie state with the login tab We’ve tried explicitly setting "credentials": "include" in the request but that still didn’t share the cookie in the extension context in the non-default profile. My questions: Is there away to allow cookie-based session sharing between a tab and an extension in non-default profiles in safari? Would switching to a token-based auth mechanism (e.g., Bearer tokens ) be the recommended workaround? I’d appreciate any insights or guidance from those who’ve run into similar issues. 
 Thanks in advance!

Safari Does Not Include topOrigin in WebAuthn clientDataJSON Despite crossOrigin: true
Hello, I’m working on a cross-origin WebAuthn implementation where a parent page embeds an iframe from a different origin to perform authentication. According to the WebAuthn Level 3 spec (Section 7.1.1), when crossOrigin is true, the clientDataJSON may include topOrigin—but Safari does not seem to populate this field. Observed Behavior: Chrome/Firefox: Include topOrigin in clientDataJSON when crossOrigin: true. Safari (macOS/iOS): Omits topOrigin even though crossOrigin is correctly set to true. Example clientDataJSON from Safari: { "type": "webauthn.get", "challenge": "...", "origin": "https://iframe-origin.example.com", "crossOrigin": true // Missing `topOrigin` (expected: parent origin) } Questions: Is this an intentional omission in Safari for privacy/security reasons? Are there specific requirements (e.g., HTTP headers, permissions policies) needed for Safari to expose topOrigin? Is there a known workaround to reliably obtain the top-level origin in cross-origin WebAuthn flows? System Info: Version 18.4 (20621.1.15.11.10) OS: Sequoia Version 18.4 (20621.1.15.11.10) Reproduction Steps: Parent page (https://parent.example.com) embeds an iframe (https://webauthn-rp.example.com). The iframe calls navigator.credentials.get() with a WebAuthn challenge. Safari returns clientDataJSON with crossOrigin: true but no topOrigin. Code Snippet (iframe): const credential = await navigator.credentials.get({ publicKey: { challenge: new Uint8Array(/* ... */), rpId: 'webauthn-rp.example.com', allowCredentials: [], hints: [], userVerification: "preferred", } }); console.log(JSON.parse(atob(credential.response.clientDataJSON))); Has anyone encountered this? Any insights would be greatly appreciated!

Safari 18.2 and macOS Sequoia 15.2 Download Issue in AngularJS Application
We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked. There are no errors in the browser console, and the download does not occur. Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected. However, the problem reappeared on Safari 18.4 with Sequoia 15.4. We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction. We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.

SpringBoard Watchdog Timeout (180s) when using "Add to Home Screen" - iOS 2026
Reporting a consistent system-wide freeze followed by a Kernel Panic when attempting to use the "Add to Home Screen" feature in Safari. This issue has persisted across multiple recent iOS updates and leads to a device bootloop. Technical Details: The UI becomes entirely unresponsive for exactly 180 seconds. Analytics logs indicate a userspace watchdog timeout caused by SpringBoard failing to check in. Panic String: panic(cpu 0 caller 0xffffffff0422ccb9): userspace watchdog timeout: no successful checkins from SpringBoard (0 induced crashes) in 180 seconds Steps to Reproduce: Open Safari and navigate to any URL. Tap the Share icon. Select Add to Home Screen. The device UI freezes immediately. After 3 minutes, the system triggers a reboot. Environment: • Device: 16PM panic-base-2026-03-12-222721.ips.txt • OS Version: 26.4 RC and Beta 3 v1 • Feedback ID: FB22286846 (Full sysdiagnose and panic logs are attached to the original Feedback Assistant report). Questions: Is this a known regression involving the web clip background daemon, or does the 180s timeout suggest a specific database corruption within the Home Screen layout?

After iOS 18.4, files are called multiple times in WKWebView
Since the transition to iOS 18.4, we have been having an issue where when loading an m3u8 file specified in the src attribute of a video tag in WKWebView, the ts file is loaded repeatedly. Are there any good ideas for this? Also, if there have been any changes to the specifications of WKWebView, we would appreciate it if you could let us know.

SwiftUI WebView: Is action.target == nil a Reliable Way to Handle New Window Requests?
In WKWebView, there is the WKUIDelegate method: func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {} This delegate method provides a callback when a new window (for example, target="_blank") is requested in the web view. However, in native SwiftUI (iOS 26), WebView / WebPage APIs do not provide an equivalent delegate method to handle new window requests. As a workaround, I am using the following method: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {} In this method, when action.target == nil, I treat it as a new window request. My question: Is relying on action.target == nil in decidePolicy a reliable and future-safe way to detect new window requests in SwiftUI’s WebView, or is there a better or more recommended approach for handling target="_blank" / new window navigation in the SwiftUI WebView APIs? Code: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy { guard let webPage = webPage else { return .cancel } // Handle case where target frame is nil (e.g., target="_blank" or window.open) // This indicates a new window request if action.target == nil { print("Target frame is nil - new window requested") // WORKAROUND: Until iOS 26 WebPage UI protocol is available, we handle new windows here // Try to create a new WebPage through UI plugins if handleCreateWebPage(for: webPage, navigationAction: action) != nil { // Note: The new WebPage has been created and published to the view return .allow } } return .allow }

To reproduce this request (with the previous DNR rule in place) : navigate to https://www.qwant.com search for some string (test in my case). This displays the list of results ; click the engine button at the top right to display the settings pane ; inspect network request performed by this page ; change the Adult filter in the list -> the results are automatically updated with the new settings. The web request shows URL with the 2 safesearch parameters. I already used addOrReplaceParams in 'standard' contexts (main_frame) and it works just fine. Any hint on what goes on ? Thank you.

Incorrect page zoom after pinch-to-zoom and orientation change on Bing search page
Steps to Reproduce: Open the Bing search page in Safari (example URL: https://www.bing.com/search?q=webkit&form=APIPH1&PC=APPL). Pinch-zoom in or out, then return the page to exactly 100% zoom. Rotate the device from portrait to landscape orientation. Observe that the page is incorrectly scaled to a value other than 100%. Rotate the device back to portrait orientation. The page remains at the incorrect zoom level. Expected Result: After returning the page to 100% zoom, changing orientation should keep the zoom level at exactly 100% in both portrait and landscape modes. Actual Result: After returning to 100% zoom, rotating to landscape changes the zoom to a non-100% value, and rotating back to portrait retains the incorrect zoom level.

Extension in Safari Fails Auth in Non-Default Profile When Using Cookie-Based Mechanism
Hello, We are developing a Safari Web Extension that uses a cookie-based authentication mechanism. The extension makes a request to an endpoint e.g. /login, and this endpoint expects a cookie (e.g., sessionId) to be included with the request. Everything works correctly when running in the default Safari profile. However, when I install and run the same extension in a new, non-default profile, the behaviour changes: The request to /login is still made The cookie sent is not as expected As a result, the response returns null user data I confirmed that logging into the site in the new profile (in a tab) works, but the extension does not appear to share the session/cookie state with the login tab We’ve tried explicitly setting "credentials": "include" in the request but that still didn’t share the cookie in the extension context in the non-default profile. My questions: Is there away to allow cookie-based session sharing between a tab and an extension in non-default profiles in safari? Would switching to a token-based auth mechanism (e.g., Bearer tokens ) be the recommended workaround? I’d appreciate any insights or guidance from those who’ve run into similar issues. 
 Thanks in advance!

How can I make an background image take up full screen space on ios26
How can I make a background image take the entire screen in ios26? I've tried position fixed, sticky, env() css variables but nothing worked. It does it when in PWA mode, but I would like to do so in the browser too.

Safari Does Not Include topOrigin in WebAuthn clientDataJSON Despite crossOrigin: true
Hello, I’m working on a cross-origin WebAuthn implementation where a parent page embeds an iframe from a different origin to perform authentication. According to the WebAuthn Level 3 spec (Section 7.1.1), when crossOrigin is true, the clientDataJSON may include topOrigin—but Safari does not seem to populate this field. Observed Behavior: Chrome/Firefox: Include topOrigin in clientDataJSON when crossOrigin: true. Safari (macOS/iOS): Omits topOrigin even though crossOrigin is correctly set to true. Example clientDataJSON from Safari: { "type": "webauthn.get", "challenge": "...", "origin": "https://iframe-origin.example.com", "crossOrigin": true // Missing `topOrigin` (expected: parent origin) } Questions: Is this an intentional omission in Safari for privacy/security reasons? Are there specific requirements (e.g., HTTP headers, permissions policies) needed for Safari to expose topOrigin? Is there a known workaround to reliably obtain the top-level origin in cross-origin WebAuthn flows? System Info: Version 18.4 (20621.1.15.11.10) OS: Sequoia Version 18.4 (20621.1.15.11.10) Reproduction Steps: Parent page (https://parent.example.com) embeds an iframe (https://webauthn-rp.example.com). The iframe calls navigator.credentials.get() with a WebAuthn challenge. Safari returns clientDataJSON with crossOrigin: true but no topOrigin. Code Snippet (iframe): const credential = await navigator.credentials.get({ publicKey: { challenge: new Uint8Array(/* ... */), rpId: 'webauthn-rp.example.com', allowCredentials: [], hints: [], userVerification: "preferred", } }); console.log(JSON.parse(atob(credential.response.clientDataJSON))); Has anyone encountered this? Any insights would be greatly appreciated!

Safari 18.2 and macOS Sequoia 15.2 Download Issue in AngularJS Application
We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked. There are no errors in the browser console, and the download does not occur. Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected. However, the problem reappeared on Safari 18.4 with Sequoia 15.4. We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction. We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.

SpringBoard Watchdog Timeout (180s) when using "Add to Home Screen" - iOS 2026
Reporting a consistent system-wide freeze followed by a Kernel Panic when attempting to use the "Add to Home Screen" feature in Safari. This issue has persisted across multiple recent iOS updates and leads to a device bootloop. Technical Details: The UI becomes entirely unresponsive for exactly 180 seconds. Analytics logs indicate a userspace watchdog timeout caused by SpringBoard failing to check in. Panic String: panic(cpu 0 caller 0xffffffff0422ccb9): userspace watchdog timeout: no successful checkins from SpringBoard (0 induced crashes) in 180 seconds Steps to Reproduce: Open Safari and navigate to any URL. Tap the Share icon. Select Add to Home Screen. The device UI freezes immediately. After 3 minutes, the system triggers a reboot. Environment: • Device: 16PM panic-base-2026-03-12-222721.ips.txt • OS Version: 26.4 RC and Beta 3 v1 • Feedback ID: FB22286846 (Full sysdiagnose and panic logs are attached to the original Feedback Assistant report). Questions: Is this a known regression involving the web clip background daemon, or does the 180s timeout suggest a specific database corruption within the Home Screen layout?

After iOS 18.4, files are called multiple times in WKWebView
Since the transition to iOS 18.4, we have been having an issue where when loading an m3u8 file specified in the src attribute of a video tag in WKWebView, the ts file is loaded repeatedly. Are there any good ideas for this? Also, if there have been any changes to the specifications of WKWebView, we would appreciate it if you could let us know.

SwiftUI WebView: Is action.target == nil a Reliable Way to Handle New Window Requests?
In WKWebView, there is the WKUIDelegate method: func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {} This delegate method provides a callback when a new window (for example, target="_blank") is requested in the web view. However, in native SwiftUI (iOS 26), WebView / WebPage APIs do not provide an equivalent delegate method to handle new window requests. As a workaround, I am using the following method: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {} In this method, when action.target == nil, I treat it as a new window request. My question: Is relying on action.target == nil in decidePolicy a reliable and future-safe way to detect new window requests in SwiftUI’s WebView, or is there a better or more recommended approach for handling target="_blank" / new window navigation in the SwiftUI WebView APIs? Code: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy { guard let webPage = webPage else { return .cancel } // Handle case where target frame is nil (e.g., target="_blank" or window.open) // This indicates a new window request if action.target == nil { print("Target frame is nil - new window requested") // WORKAROUND: Until iOS 26 WebPage UI protocol is available, we handle new windows here // Try to create a new WebPage through UI plugins if handleCreateWebPage(for: webPage, navigationAction: action) != nil { // Note: The new WebPage has been created and published to the view return .allow } } return .allow }
