What browser are you using? Google has been known to make YouTube perform worse on browsers that aren’t Chrome.
- for videos
- for website rendering
AFAIK the video acceleration part is the big problem as the issue was ignored for many years by the browser vendors. For rendering websites most browser should do just fine, some hardware-browser combinations might be exceptions though.
I also wonder what you mean by Firefox has no user profiles, because Firefox has a profile concept too. Be default it doesn't ask you, but when you start it with `firefox --ProfileManager` you will see what I mean. I don't like messing with the Profile Manager every time, so I just have different Icons for starting different Profiles (e.g. Music --> Spotify, Movies --> Amazon & Netflix, etc.).
Currently there are just two websites for which I have to use Chromium:
1. Geforce Now, officially Linux is not supported, but with Chromium it does work when you change your user-agent
2. Binance, for whatever reason their login capture doesn't work with Firefox
On the profiles part: I am aware of the --ProfileManager option. But the icon is new to me. Should be worth trying. Thanks. Work uses G Suite so I don't know how Meet + some other tools react with Firefox.
chrome://gpu/ -- here you can see the current status of your GPU Acceleration
chrome://flags/ -- search for 'GPU' or 'accel'. This is the place where you can override some related settings, but be aware, that this might break your browser, so better backup your browser configuration directory before changing anything ;-)
