I have a very repeatable issue, that others have been dealing with as well, where Firefox will frequently disconnect Twitch chat after a period of time and go through a loop of disconnecting/reconnecting. This is ONLY on Firefox, I can run Chrome or other browsers simultaneously with Firefox and Firefox will disconnect when others do not. I am not sure what is occurring, but I know it only happens after a while. Like maybe after 30+ minutes of watching a stream, the chat will start skipping other users inputs, just show my own, then give me a Welcome to the chat connection and other messages will start appearing again. Once it hits this hang-up period, it starts disconnecting frequently. I cannot find any resolution and there are no resources or articles about this, but I made a post on reddit and multiple users reported the same thing.
