Thank you! Found out PerformanceObserver is required for github to work!

Hi. I just want to say thank you for linking this site in your readme, it's how I've determined why github seemed mostly broken and not even jumping to tags properly (like 'url#post_or_event') and appearing to be needing a page refresh to even see any updates/new_comments on an issue or PR (and possibly also the reason I wasn't seeing any review comments if the review wasn't finished? unless that's normal) or even seeing that there are new notifications blue dot. EDIT: Also, if I pressed the 'star' button on a repo, it would redirect me to my dashboard page, then I'd press back and still see the repo unstarred so an F5 to refresh was needed! EDIT2: also, couldn't set status at all.

It was because a required feature PerformanceObserver was disabled by me (to make too sure that I avoid any Spectre issues, I guess; even though I'm aware that the high resolution part was already changed by the FF devs, to be no less than 1ms for that spectre mitigation) in about:config of Firefox like dom.enable_performance_observer=false, but it should be true and now things appear to work as they should!

Btw, if you could write this text from the repo's readme:

If you would like to see what features the browser you are currently using implements, you can visit the documentation site which displays a compatibility table that detects which features are natively supported in your browser.

in this doc: https://docs.github.com/en/get-started/using-github/supported-browsers
that would be even better!
