Browser Support Request: Safari 14

[docyx]

(this is not an actual issue, just a request, so I removed the template)

uBlock hasn't worked on Safari for a while now, since Apple used a proprietary extension API which caused a lot of issues. more info.

With the new Safari 14 release, it now supports the WebExtensions API. Since uBlock uses this API, it would be really nice to have uBlock on Safari now that it supports it.

Also time to update https://github.com/gorhill/uBlock/blob/master/platform/safari/README.md#safari-platform as well (:

One year later with newer versions available I checked again but it seems like most of the necessary WebExtensions APIs are still not supported.

Tested with Safari 15, Xcode 13 and uBlock Origin 1.38.0, all newest production versions available at time of writing.

Compatibility check with xcrun safari-web-extension-converter ./uBlock0.chromium/ gives:

Hello,
I attempted to convert the extension. Most APIs should be supported now. The lack of storage and webRequestBlocking might be annoying, but there are probably some workarounds for this.

The lack of ... webRequestBlocking might be annoying

The main feature?

https://browser.kagi.com/faq.html if you really need to use webkit, but with ublock origin. Still kinda beta so not perfect yet but seems like a solid project. I used app a bit and it feels like using safari, but it does lag behind on feature support. I could not get push notification api to work with it yet for example.

Hey! Recently switched to uBlock and must say I really like it. Are there any updates on this issue? Is WebKit/Safari getting more of the APIs needed?

Safari supports declarativeNetRequest, which is the modern replacement for webRequestBlocking: https://developer.apple.com/documentation/safariservices/safari_web_extensions/blocking_content_with_your_safari_web_extension

Is there a reason declarativeNetRequest cannot be used?
