Yesterday I was watching stuff online as usual when suddenly all videos stopped playing, even YouTube videos would only buffer 10-20 seconds and then stop. I normally use Firefox, so I switched to Chrome, and this problem didn’t happen so I can rule out connection or bandwidth problems.
I have noticed that there are some weird processes appearing in the task manager in addition to a high CPU usage when I start Firefox. It’s nearly 100% all the time! I tried uninstalling and reinstalling Firefox, disabling some add-ons, but nothing worked.
Could it be some kind of a bug or malicious program that got stuck on Firefox ? I really need help because I love Firefox and this just sucks.
