Why does my Firefox keep freezing when watching videos, scrolling, or even typing something?

This just recently started happening, whenever I'm browsing a webpage and scrolling through it. Firefox will freeze for about 1-2 seconds than continue scrolling. The same happens when I'm typing something. It's frozen about 3 times so far since I started typing this. Also when I watch any video, the video will freeze too. It freezes for basically anything I do. I know it's not my computer because I put a video I have stored on my hard drive, playing on the side of Firefox and every time the Firefox froze, the video continued to run smoothly. This is really annoying! I have the latest version of my plugins and the latest version of Firefox. How can I fix this?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).


Try to disable hardware acceleration.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
