I want to be able to recommend firefox to everybody, but after 15 years of chrome and going back to firefox, it still feels jank.

Web apps like twitter youtube discord that is left open for a few hours take up >2gb ram and is jittery. I have to shift+esc and close them to make them run smoothly again. Why hasn't stuff like this been fixed yet?

Why do I need to open about:profiles just to launch a new profile?
