firefox clogs disk

Hello. Firefox quickly takes up all the space on the SSD. After about two days of work, there is no disk space left. Closing the browser helps, but it's not comfortable. Windows 10 system.

Start Firefox in Safe Mode {web link}

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

I am not understand. why run in safe mode? Firefox is working fine, it is occupying the disk. SSD 120 GB. Free 85 GB. After two days of continuous operation, free space is 0.

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes), any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem. If the problem goes away, that tells us one thing. If it does not, that tells us something else.

How do you know Firefox is filling the disk? Is TRIM enabled for your SSD?

Killing the firefox.exe process frees up space. Trim included

Perhaps you need to reduce the about:config setting "browser.cache.disk.capacity". Edit: On second thoughts, that setting is unlikely to be as high as the usage you say is happening. I have mine set in megabytes, NOT gigabytes. You could look at other browser.cache settings also.

This usually happens at night when the computer is locked and not in use.

Is there a reason you leave the browser running? As a test, shut down Firefox when not in use.
