Hello. I ve got a big problem on my Firefox browser. When im using other browsers i dont have this problem, it s only on Firefox, but i love using Firefox and i want to fix it.

Problem which i have shows up on youtube and sometimes on twitch. When im watching youtube video in vp09 format there are absolutely no problems with frames but when a video is in avc1 format - boom i cant watch it because of super frame drops - like a 90% of total frames are dropeed.

Example video: https://www.youtube.com/watch?v=xr-zCc9VUto

My pc is not the best but not the worst, i dont think its hardware problem because as i said, on other browser i dont have this problem watching the same video it isnt dropping frames. CPU: Xeon X5450 GPU: GTX 660Ti RAM: 8GB

This problem is with me since about a year, i dont know when it happened. Please help me, how to fix it?

I mean that it shouldn't be Basic in the first line. You don't use GPU and performance is very weak.

Okay i fixed it by enabling OpenGL - changing layers.acceleration.force-enabled in about:config to true. It seems to be working properly now but i dont know why couldnt you just say that and help me fix this problem instead of saying "everything is messed up" lol it was only 1 rule to change and now everything s working
