Css fieldset/legend with flex and float bug
When I want legend inside the filedset, not on the border as default browsers design, I set float: left to the legend. It works in every modern browser - Safari too. The problem is when the filedset itself is set to display: flex. Float propertie of the legend is ignored. In other browsers this approach works fine and the float stays and the legend is inside of the fieldset as we expect.

Unclear interimResults Web Speech API implementation in Safari iOS (WebKit)
Hi all! I have been working on a web speech recognition service using the Web Speech API. This service is intended to work on smartphones, primarily Chrome on Android and Safari (or WebKit WebView) on iOS. In my specific use case, I need to set the properties continuous = true and interimResults = true. However, I have noticed that interimResults = true does not always work as expected in WebKit. I understand that this setting should provide fast, native, on-device speech recognition with isFinal = false. However, at times, the recognition becomes throttled and slow, yielding isFinal = true and switching to cloud-based recognition. To confirm whether the recognition is cloud-based, I tested it by disabling the internet connection before starting speech recognition. In some cases, recognition fails entirely, which suggests that requiresOnDeviceRecognition = false is being applied. (Reference: SFSpeechRecognitionRequest.requiresOnDeviceRecognition) I believe this is not the expected behavior when setting interimResults = true. I have researched the native services used by the Web Speech API on iOS devices, and the following links seem relevant: • SFSpeechRecognizer • SFSpeechRecognitionRequest.shouldReportPartialResults • SFSpeechRecognizer.supportsOnDeviceRecognition • Recognizing speech in live audio • Apple Developer Forums Discussion I found that setRequiresOnDeviceRecognition and setShouldReportPartialResults appear to be set correctly, but apparently, they do not work as expected: WebKit Source Code

Inquiry regarding /Library/Preferences/com.apple.networkd.plist
I have a question. In the file located at /Library/Preferences/com.apple.networkd.plist, if the dict entry for enable_unified_http is set to true or if the value is missing, there is an issue where the video player does not run on MacOS Sequoia Safari 18.0. I found that setting it to false allows it to function properly. Could you explain what this setting does and whether it is possible to change this setting to false within the app?

Safari-Specific React Animation Issues: Infinite Scroll Breaking on MacBook
I'm encountering a browser-specific issue with a React infinite scroll animation component. The animation works perfectly in Chrome on MacBook, but breaks specifically in Safari: ✅ Chrome on MacBook: Works perfectly ❌ Safari on MacBook: Animation and layout issues Technical Details Environment Browser: Safari: Version 18.1.1 (20619.2.8.11.12) MacBook 13-inch display React 18 GSAP for animations TailwindCSS for styling Next.js/TypeScript project Implementation const MovingGrid: React.FC = () => { useEffect(() => { const initAnimation = () => { const container = containerRef.current; if (container) { gsap.to(container, { x: `-${firstSet.clientWidth}`, duration: 30, ease: "none", repeat: -1, onRepeat: () => { gsap.set(container, { x: 0 }); } }); } }; }, []); return ( <div className="hidden lg:block overflow-hidden w-full relative"> <div ref={containerRef} className="flex absolute -bottom-[100px]"> {/* Grid content */} </div> </div> ); }; Safari-Specific Behavior Images overflow the container in Safari only Layout gets disrupted when animation resets Same code works perfectly in Chrome on the same machine Cross-Browser Testing Results Safari on MacBook: Issues with animation and layout Chrome on MacBook: Works as expected Firefox on MacBook: Works as expected Safari on iOS: Needs testing Chrome on Windows: Works as expected Attempted Solutions Safari-specific CSS fixes: /* Attempted Safari-specific fixes */ @supports (-webkit-hyphens:none) { .moving-grid { transform: translateZ(0); -webkit-transform: translateZ(0); backface-visibility: hidden; -webkit-backface-visibility: hidden; } } Modified GSAP configuration for Safari: gsap.config({ force3D: true }); Tried various CSS transform and positioning approaches: className="transform will-change-transform" style={{ WebkitTransform: 'translate3d(0,0,0)' }} Questions Are there known Safari-specific issues with GSAP animations that require special handling? Does Safari handle infinite scroll animations differently from Chrome in terms of performance or rendering? Are there recommended Safari-specific optimizations for smooth animations? Should we implement a different animation approach specifically for Safari users? Investigation Notes Performance metrics show no significant issues Animation frame rate is consistent Layout calculations appear correct before animation starts Impact This issue affects a crucial part of our property showcase website, specifically impacting Safari users on MacBook devices. Given Safari's significant user base on MacBooks, this needs to be resolved for a consistent cross-browser experience. Additional Context The animation is part of a larger property showcase feature Performance is crucial for user experience Need to maintain visual consistency across browsers Reproduction Steps Open website Safari on MacBook [pinkdoorbnb .com] Observe the infinite scroll animation Compare with Chrome on the same device Note the differences in animation behaviour and layout I would greatly appreciate any insights into Safari-specific animation handling or alternative approaches that work consistently across browsers. Here is sample Google Chrome ⬇ Safari ⬇

Safari 18: Storage location for open windows and tabs
I want to write an app, that lets users restore all oben windows and tabs from any given point in a TimeMachine backup. The store location seems to have changed. In earlier versions it was possible to restore the open windows and tabs by retrieving /Users/[UserName]/Library/Containers/com.apple.Safari/Data/Library/Safari/SafariTabs.db …/SafariTabs.db-shm …/SafariTabs.db-wal As of 18.3 this doesn’t work any more, even though these files get updated with the use of Safari What else would I need to retrieve from a back up disk? Thank you very much for any hints!

ServiceWorkers is not working in iFrame
I have tried to initialize service workers, but they only work in the WebView. When I open an iframe from that WebView, they do not function. Below is my implementation. Is this an issue because iOS does not support service workers in iframes? Please help me answer this. :man-bowing: self.addEventListener('install', event => { // Apply this service worker immediately self.skipWaiting(); }); const putInCache = async (request, response) => { const cache = await caches.open("v1"); await cache.put(request, response); }; const customCache = async ({ request, preloadResponsePromise }) => { }; self.addEventListener("fetch", (event) => { event.respondWith( customCache({ request: event.request, preloadResponsePromise: event.preloadResponse, }), ); });

DNR Redirect Rule Won’t Redirect to Extension Path
DNR rules redirecting to an extension path lead to an error page: “Safari can’t open the page. The error is: “The operation couldn’t be completed. (NSURLErrorDomain error -1008.)” (NSURLErrorDomain:-1,008).” Here is a demo extension that replicates the bug: https://github.com/lenacohen/Safari-Test-Extensions/tree/main/dnr-extension-path-redirect This is an example of a redirect rule that leads to an error page instead of the extension path page: chrome.declarativeNetRequest.updateDynamicRules({addRules: [ { id: 2, priority: 1, action: { type: "redirect", redirect: { extensionPath: "/web_accessible_resources/test_redirect.html" } }, condition: { urlFilter: "||washingtonpost.com^", resourceTypes: [ "main_frame" ] } } ]}); The extension path is included in web_accessible_resources in the extension manifest: "web_accessible_resources": [{ "resources": [ "web_accessible_resources/test_redirect.html" ], I also submitted a bug report on Apple's Feedback Assistant: FB16607632

Discrepancy in Cookie Consent Options Across iOS 18.0 and 18.1 on Certain Websites
I've observed a discrepancy in cookie consent options between iOS 18.0 and 18.1 on some websites, such as www2.hm.com. On iOS 18.0, I see "Accept All Cookies" and "Only Required Cookies" options, whereas on iOS 18.1, the options change to "Accept All Cookies" and "Cookie Settings." I would like to understand if this behavior is related to differences in how websites detect the operating system version (iOS 18.0 vs. 18.1) or browser changes within the iOS update. Has anyone else experienced similar variations in cookie consent banners, and could this be tied to differences in the user agent or website A/B testing for different OS versions? Any insights or technical clarifications would be appreciated!

Issue with SKAdNetwork 4.0 for Web Ads
I have an issue with web ads not working in Safari versions earlier than 16.4. While debugging Safari Web Ads I found out that I don't get postbacks from versions 16.4 or below from Safari, although there are no technical limitations and the documentation says that web ads should work starting from versions 16.1 https://developer.apple.com/documentation/storekit/skadnetwork/skadnetwork_release_notes/skadnetwork_4_release_notes For ads that appear in an app, the app is built with iOS 16.1 SDK or later. For web ads, the ad appears in Safari 16.1 or later.`` Maybe I missed something and Apple didn't update the documentation, is that normal? Maybe it's related to this release and there was a technical problem with Apple? https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-16_4-release-notes/#SKAdNetwork Has anyone encountered the same problem and how did you fix it? Thanks!

LocalStorage sometimes disappears in WKWebView
I am currently publishing an application that uses WebView, I am currently publishing an application that uses WebView, but I am having trouble with data in LocalStorage sometimes disappearing. The website displayed in WebView is made with PHP, By writing the following code in JavaScript, When WKWebView is opened, localStorage is saved and retrieved. window.localStorage.setItem('isAlreadyAgree', true); window.localStorage.getItem('isAlreadyAgree'); The problem is that sometimes this getItem does not get the data. ・This is not reproducible and does not always occur when some process is performed. ・Is it possible that the storage of the application is cleared due to distribution using MDM? ・Is it possible to store too much data in UserDefault, which would cause the LocalStorage space to be overwhelmed and disappear? I would appreciate any hints you can give me. Thank you in advance.

Is there a way to detect the activation of "Safari's advanced protection against the tracking ..." ?
When creating an AddtoCalendar (ics, google, yahoo, outlook) Safari detects tracking only for outlook.live and outlook.office via the url used to add an event to the online calendar. I would like to inform web users that if this option is activated and they want to add the event to their online outlook calendar, they will need to temporarily deactivate this security feature! Is it possible to detect this option in jsx? Would there be a solution, like requesting authorisation to locate on a website, to allow only this url or this site (outlook.live or outlook.office) for tracking? I'm obviously thinking of something simple for the web user: a button to click.
