Firefox running extremely slow
Hello all, I've yet to test this in great detail. But, it would appear that Firefox is running super slow. It's using about 3GB of ram out of my 16GB (Seems low imho).
When opening websites like Facebook, videos, the message box etc lags. On YouTube videos can lag, and other sites that have elements that popup etc seem to lag.
I only run an AdBlock, and it's even disabled on the pages that lag. These issues aren't present in Google Chrome or Edge. In fact, Facebook is super responsive in Chrome.
I've tried various things to solve it mentioned on this forum, including entering some urls to access more advanced settings which hasn't worked.
Thanks alot.

Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Could you please run a tool from http://memtest.org/
in order to check the integrity of your RAM?
You will need a thumb or disk drive to install it on.
Do you let Windows handle the page file or did you set a fixed size ?
If you use a fixed size for the page file then try the former and let Windows handle the page file.

I ran a windows memory diagnostic, it didn't find any errors. As for the Page File, I can't remember. How could I check this, thanks.
Did you check the Firefox Task Manager (about:performance) page and possibly the about:memory page ?
