cache size error

Hi there,

I cleared my cache after it told me it had stored a gazillion GB in data - but the big number was still there after clearing the cache. Needless to say my harddrive isn't even as big as the GB number shown, so there must be a gremlin in there somewhere? Thought you'd want to know. I'm using the latest Firefox on Mac OS 10.15.7

Thank you. I was able to follow the steps until I opened the folder, however, it was empty (there was no cache/cache2 folder or anything in the folder that opened). In the end, I decided to delete and re-install Firefox, and so far it looks like that did the trick. The cache size now shows as relatively normal.

Location of the cache/cache2 folder; Windows: *C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\ Mac: ~/Library/Caches/Firefox/Profiles/ Linux: ~/.cache/mozilla/firefox/

Close Firefox. Open your file browser to the above and remove the folder.

Hi Fred,

Thank you for your response. I've tried locating this folder to remove it, but there is no "Firefox" folder under any of the Caches folders i could find...

Type about:profiles<enter> in the address box. Look for the profile with this heading: This is the profile in use and it cannot be deleted. On the line: Local Directory go to the far right and press Open Folder.

Close Firefox. Wait for the browser to finish closing (slow count of 5-7) Delete the cache/cache2 folder.

Note that the data shown as Cookies and Site Data is stored in the storage folder in the storage folder (indrexedDB) in the main profile folder and not in the browsing cache.

You can check for issues with Storage (indexedDB) if it happens again.

Thanks for all your help. The re-install fix was only temporary, the issue re-occurred after using Firefox / re-opening tabs. However, the most recent Firefox update seems to have resolved it, as i don't see a huge cache listing anymore. Thanks again.
