Firefox according to task manager is using around 3gig of ram. I'm having trouble clicking on anything because there is a delay. I've uninstalled what few add-ons i had and no improvement. My pc is Intel I59400f running windows 10 with 8 gig ram plus gtx1660 super with 6gb ram too

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

MemTest LAST UPDATED : 12/04/2020 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.
