Over the last few days I've noticed that my SSD was filling up without me downloading anything, I've run virus scans, checked the health of the SSD to find no issues, then today I closed Firefox and checked File Explorer to see the space had returned. Have no idea why Firefox is now consuming space and nothing I've tried has worked, any help would be greatly appreciated.
The maximum browser storage space is dynamic — it is based on your hard drive size. The global limit is calculated as 50% of free disk space. In Firefox, an internal browser tool called the Quota Manager keeps track of how much disk space each origin is using up, and deletes data if necessary.
So if your hard drive is 500 GB, then the total storage for a browser is 250 GB. If this is exceeded, a process called origin eviction comes into play, deleting an entire origin's worth of data until the storage amount goes under the limit again. There is no trimming effect put in place to delete parts of origins — deleting one database of an origin could cause problems with inconsistency.
There's also another limit called group limit — this is defined as 20% of the global limit, but it has a minimum of 10 MB and a maximum of 2 GB. Each origin is part of a group (group of origins).
Dunno yet, just restarted to remove all the stuff from malwarebytes scan, still showing my ssd space is dropping was at 14.9gb upon restart, at 14.6 currently. Of which chrome didn't give back any space after closing it before restart, while Firefox did. I just cannot figure out what is going on.
Would vary the long it was on, two days ago I left for a few hours and came back to 10gb eaten up. The ssd is small, a 120gb one that came when purchased the pc. Currently from reboot of 14.9 am at 14.2 now.
There's a 1tb hard drive also in the pc, but I've been running well below 15gb for months, all that changed was I updated a few days ago and this space issue started. I use utorrent, but I've not used it for weeks or have anything downloading/uploading there,
your ssd might run faster too with more free space
I only have windows + any applications that would need to be reinstalled with windows, on my ssd. Probably gone a little far, I normally have over 160gb free. I have moved all library folders, all steam games. Onedrive folder, everything I can run off hdd, I do.
