Firefox use so much memory, especially Facebook, and it dunno release memory!
I am using MacOS Catalina latest version, and I found that Firefox use so much memory, especially Facebook, and it dunno release memory! First, after open Facebook page, and scroll just a few sec then the memory quickly up to over 1gb(2.xxgb as I saw max), I use new MS Edge to compare, the memory usage of Facebook around 5xx - 7xxmb, and if I goto another group/refresh page, MS Edge will release some memory, but Firefox still keep over 1gb/2gb, won't release memory. Other website memory usage also higher compare to MS Edge, what is the problem?
P.S. I didn't install any plugin!
