Reply to Safari Web Extension tab ids are 0 during webNavigation callbacks until onCompleted event

Can not reproduce this in Safari 18.4. Is this still an issue? Did other extension APIs other than the webNavigation API return tabId of 0 instead of -1?

Reply to iOS simulator 18.4 cannot add extension to safari

It happens both on new and existing projects. Extensions load fine in the iOS simulator 18.3 even on Xcode 16.3. So the issue seems to be specifically related to iOS 18.4.

Reply to Dark mode for extension popups

Sample extension can be found in the feedback assistant or using this link: https://static.jeurissen.co/9612492-apple-darkmode-issue.zip In Chrome and Firefox, in dark mode the extension colors green. Yet in Safari it is blue. Basically it doesn't recognise the dark mode media query.

Reply to [bug] Extension frames fail to be embedded on websites

A sample extension is available in the feedback assist ticket and with this URL: https://static.jeurissen.co/8986072-apple-frame-issue.zip In browsers like Firefox and Chrome. The frame is loaded and says "frame". In Safari it doesn't load and thus is blank.

A sample extension can be found here: https://static.jeurissen.co/9612454-apple-sandbox-issue.zip In Chrome and Firefox, "loading..." changes to "loaded". Not in safari due to this issue. The script simply doesn't load.

Reply to Safari web extension - background script - sessionStorage

I'm suggesting to switch to the browser.storage / chrome.storage API. In some other browsers / future browsers support for sessionStorage and localStorage is dropped for extensions. See: https://groups.google.com/a/chromium.org/g/chromium-extensions/c/6qiMo0P-XS4
