I have about 25 extensions (almost all needed) and firefox lags like crazy, it’s like I’m watching the videos at 10 fps. I download chrome to test it out and sure enough it runs as smooth as butter. Any help?
EDIT: It somehow fixed itself after I started using LibreWolf (with the same addons)
Could be any number of things. Possibly a bad plug in or combination of plug-ins. Could be your new video card didn’t jive with your installation of Firefox.
Run Firefox in safe mode and see if the performance improves. If it does, you likely have a plugin causing the issue. From there, disable all of them and reenable them one at a time to see if the problem comes back.
Disable and reenable hardware acceleration.
Disable ipv6 This is an issue I ran into earlier this year.
Clear cache and cookies
And last resort, Uninstall Firefox and all profiles and settings and reinstall a fresh copy. (after syncing your account, obviously)
I always run with hardware acceleration off on all my Firefox machines, it seems to cause a lot of issues and the videos play just fine without it.
Depends on the setup. Disabling it on mine turns Firefox into a slideshow.
