"28.0 KB of Disk Space" Will Not Clear
I regularly clear "Cookies and Site Data," but recently instead of cache going to 0 KB, it first started remaining at 3KB. It has now increased to read "Your stored cookies, site data and cache are currently using 28.0 KB of disk space." What is that 28 KB, why can I not clear it, and do I need to be concerned about it anyway? There are no websites listed in "Manage Cookies and Site Data," and clicking on "Remove All" does nothing to clear the 28KB.
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.
You can use the Local Directory button on the about:profiles page to go to the disk cache folder. Note that this might just be about some management files.
