I rage-installed Brave browser today. Been a firefox user for a long time but its getting resource hungrier and performance-worser on my laptop (linux). So far so good. Brave is fast but otherwise similar to Chrome.
This has been Friday night geek chat with Oldgreeeeeg.
Brave is Chromium based so it might be resource hungry as well. Librewolf is Firefox based with more privacy built in, you might be able to get some mileage out of that
