Hello, i have notices in the last few days that Mozilla suddenly starts stuttering and freezing, after checking the task manager i saw that for no reason used almost all my ram and ssd speed. I want to point out that that happened before i opened youtube video so i assure you this is not because of 480p youtube video(i have limited data so i watch in low quality). If someone have solution to this problem that would be nice. This happens almost every time i use Mozilla. First it starts with eating ram and after 1 minute it starts using SSD also. I couldn't take screenshot immediately because it prevented me from doing anything for at least 30 seconds, but my ram usage was 99% and after 30 seconds it dropped to 86%. I had only 4 tabs opened. Thank you for reading this, best regards and stay safe!

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 : 27/09/2013 Could you please run a tool from 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.
