I'm not sure how to get in touch with the dev of this app other than leaving a review. Overall, this extension has made Twitch an actually usable site for me. I have pretty good internet for where I live (400Mb Down, 50 Up). But, for some reason, Twitch constantly had issues. Streams would buffer, I would constantly get error 2k and error 3k codes where the site just legit gives up on trying to keep me connected. The most annoying thing is the fact that Twitch is now embedding ads into the middle of streams, disregarding what's going on and bypassing traditional addons that were normally blocked as an element of the page I assume. Alt Player legitimately erased all of those issues. I can watch a stream with no buffering and only a slight delay between chat and the stream. I Just wanted to share some issues I've been having recently with the extension that I'm sure are more to do with Twitch and Firefox than they are to do with the extension. As of today (09/23/2020) I'm getting streamer run ads and I think, Twitch ads inside alt player. As other people have mentioned I'm also experiencing the extension crashing and breaking until firefox is restarted. I assume this has to do with the firefox 80 update and not the extension. Great addon overall though. Wanted to just see if there was a way to get in touch with the dev but, since its a review, I thought it deserved a full one.
