The add-on wasn't updated in a while and straight up breaks some sites

Using it for years but i stopped using it because it's blocking twitch from fully loading, at this URL: twitch[.]tv/directory/game/Fortnite
I don't use Twitch much, but still, it's likely this extension is breaking many more websites.

Previously the add-on (seemed to) work with no issues; however, recently (perhaps of previous firefox release pre-100) it started to break some websites - specifically I cannot login to Linkedin with the add-on running
