Hi everyone, I'm on w7-64. I updated to FF86, and there were obvious problems with it, so I installed 84. Works fine, except that now I'm noticing twitter and facebook get slower over time. I didn't notice that before reinstallation of 84. I just created a new profile and refreshed. Will monitor. But what is the usual issue when firefox is doing this? Basically its not releasing memory correct? I tried useing Firemin (https://www.rizonesoft.com/downloads/firemin/), and there was a noticable difference with twitter and firefox. But I'd rather just fix the issue instead of using a bandaid if I can. During the reinstallation of FF84, I did delete a few registry entries (I followed a page like this to do it (https://www.tenforums.com/browsers-email/164280-remove-firefox-completely-then-reinstall.html)). But I don't know how that could effect releasing memory. I'll keep you updated, but does anyone have any insight? Thanks!
