If I am on Youtube and click the logo icon in the top left, or the Twitter back button, or click on a recommended video, my entire computer freezes for 8-15 seconds. I can't close apps, speak on communication apps like Discord, nor can I even close the tab. I've tried troubleshoot mode, verifying browser file integrity, turning hardware acceleration off, and using older versions of Firefox and the issue seems to persist no matter what I do, I happen to really like this browser and I really want to try and find a solution for these issues. I am always running the latest version of Firefox (90b5) and use windows 8.1. When recording some of my performance data it seems the issue uses all the power my CPU (i-5 6600k) is able to offer. I don't know how to fix this and would really appreciate any help, thank you in advance.
