For roughly three months I have been experiencing issues with Twitch.tv that I do not have on other browsers. Namely, after a random period of time the site will just "go out" on me. I can keep watching streams that are open, but any attempt to open a new window or tab results in a page with no elements loaded. During this "out" period none of my chats will send, and any other attempts to interact with Twitch will fail. After a random period of time, things will go back to normal. I've tried clearing my cache and cookies, I've tried disabling and uninstalling all of my extensions, I've tried updating the browser, I've uninstalling and reinstalling Firefox, I've tried Incognito Mode, I've tried a DNS flush, I've refreshed Firefox and it didn't work. I have found one thing that has worked though. I created two new profiles. The first had the issues occur again, but the second one hasn't experienced any of the same issues as far as I've seen, so I think the issue is with my settings. The trouble is, I don't know which setting is the issue, and deleting prefs.js doesn't appear to reset my settings, even after restarting my browser. Is there some step I'm missing regarding deleting prefs.js? Please do NOT suggest using Firefox Refresh, as I am NOT interested in going through all the steps again, especially when it didn't work at all the first time I tried.
