God I wish chrome didn’t remove manifest v2

Here is the list of things that piss me off about firefox:

• It is dogshit slow
• It eats up a ludicrous amounts of RAM, which I wasn’t expecting since it’s one of the main things people make fun of chrome for
• It crashes constantly
• It tries to push it’s “AI” bullshit on me despite me turning it off on multiple occasions
• It puts ads on my home page
• It needs to be relaunched regularly because at some point it becomes too laggy to use. It even stops loading pages altogether
• “Restore previous session” feature doesn’t work half the time so restarting the browser is absolutely terrifying
• Profile management is a mess

Are there any alternatives? Is Brave any good?
