I switched from Brave to Waterfox 6.6.13 and noticed it's burning through RAM very fast. On the screen above both Waterfox and Brave are opened in the background, with the same 3 websites open (YT playing music, Reddit and Facebook), but Waterfox using almost 3Gb RAM and 2x CPU load while Brave using just a little over 1Gb. The difference is even bigger if I open 10-15 tabs, makes me grateful for 32Gb RAM I have.

Is this normal, or is there something wrong with settings? I don't remember Librewolf using that much RAM when I tried it shortly. I use built-in adblock by Waterfox and built-in Brave shields, Win11.
