Been using this extension for years now and it worked great until recently, was really handy to be able to just look at the toolbar icon to see live channels.
Recently it has become unusable for me though, at some point I got signed out and since then whenever I try to login I get as far as the prompt page from Twitch to allow access and then a server not found error. I've tried everything and still can't get it to work so finally had to uninstall.
I'm assuming a Twitch update broke something that just hasn't been fixed yet since the last update was 5 years ago, but I can't recommend in its current state unfortunately.

The scroll to the right is bothering me so much. I used this for years on Chrome. Now that I switched to Firefox, I need it!!!

Please fix the scroll.
Other users seem to have this problem for months now.
