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 (, 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 ( But I don't know how that could effect releasing memory.

I'll keep you updated, but does anyone have any insight?
