Firefox lags when it didn't before.

Firefox has been laggy at times lately on my PC (Windows 11 Home, Firefox 152). I have tried some fixes with no success (clearing the cache, deleting YouTube cookies, using the User-Agent Switcher, etc.) Other browsers appear to be unaffected. I first noticed this on YouTube, but it seems that other websites are affected as well.

Have you tried comparing 1.) in Private Window without singing in into Youtube, and 2.) restarting intro Troubleshoot Mode to see how it performs without addons?
