Relevant WebKit commit.

Safari 18 also supports preferred_environment, which gives extensions control over this. More details here.

FYI: the section you quoted starts with this:

Report problems with this compatibility data on GitHub

And you should use that link instead, because it takes you to a different repo.

hi @Josh-Cena The issue is about the section https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/background#browser_support

not https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/background#browser_compatibility which is the one you are talking about. ❤️

Ah I see. TBH this kind of data usually lives in BCD, but this is WebExt docs so I'll peace out. Thanks for pointing out!
