I have been having this problem for about 3 months. FF is UTD. Twitch will glitch, blur, stop playing, stream go black, and get the forever load circle. My browser games will get "Not connected to the server" every few minutes and I have to reload. Facebook will tell me that I'm not connected to the internet. My browser calls glitch. Music streams and podcasts will pause for up to a minute and restart. Emails take forever to load. My computer is only about 2 years old with 16G RAM. I have none of these problems with Chrome. I ran a Twitch stream side by side on FF and Chrome today and glitches on FF while Chrome ran smoothly. When I look in task manager, FF is running anywhere from 30-50%. It shouldn't run that high. Chrome doesn't run that high with the same tabs. What is going on?
