I tried everything under the sun too. Been using brave but the web 3 crap and all their additions are getting unbearable. Bounced around between edge, librefox, firefox, operagx.

Opera GX had the best performance. It's really good at resource management and it's chromium based but NO TAB GROUPING WTF... and it looks like hot garbage.

MSFT bad edge bad, Otherwise edge had the next best performance

Google track me so chrome bad

Firefox is probably a scam and neither fox options have tab grouping either.

Degoogled chromium it is.
