So Firefox, even with few tabs open, can cause my decent PC (512GB SSD, 8GB RAM) to get rather hot, and it can slow my entire rig. I have looked at about:memory, and the memory report has attributed a gigabyte to : '132,113,458.61 MB (98.43%) ── free(segments=471)'. Now I'm no computer expert, but it reads to me that Firefox is dedicating an eighth of my RAM solely to nothing. Can I ask why this is happening and how to free up ram for other, more demanding programs?

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.
