I revisited using Hypothes.is again after not using it for a year. Finally found this extension and it works on FireFox for Windows. Haven't tried it on my Macbook M3 yet.

Thanks for Firefox users you do this and its works !
But Some time (every) I need to re login,.. lost time, not war.

Easy !

Awesome! I've been meaning to do this for years, but now I don't have to. I really don't know why an official extension doesn't exist, but either way, nice work.

Excellent! Just keep the bookmarklet, for annotating also local PDFs.

Wow! This is a really nice port, and is great for educational purposes. Thanks for making this extension available on the best browser that there is
