I am boycotting brave because of its sizeable amount of controversies and because it is American. I have decided to swap to Vivaldi but I have noticed a significant performance decrease on Speedometer 3.1 Benchmarks. Furthermore, according to EFF Cover my Tracks I now have a unique finger print and am easier to track.
My setup consists of using uBlock Origin (normal not lite) instead of Vivaldi’s built in tracker & ad blocker.
As far as I know, Chrome uses much more RAM than Firefox. Look for benchmark, Firefox keep using less RAM and being fast as Chrome, some builds even faster on the brenchmarks I read.
