After some time of use Firefox start to lag. Finally websites barely open. I tried EVERYTHING and ONLY restarting Firefox works. After restart all is good again... I use VPN.

About how long before the trouble starts?

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.
