I use Ironfox also mainly for the plugins. I have the personal stuff on my phone over Tor since I don’t want to pay for a VPN, and I’ve noticed that Ironfox is a lot slower than Vanadium/Cromite for that setup, which both also have JIT disabled

Librewolf has all of the good parts of Brave and none of the shitty parts

If all of the web engines enshittify, you can always curl the HTML/CSS/JS and hand-parse it. Might have suboptimal performance however.
