Can't clear cache

more options

I could not clear a cache, so I checked about:cache and clicked "List Cache Entries". I found the cache that I could not clear had "Pinned" in Pinning section. I searched about Pinning in about:cache, but I could not. I'd like to know in what case a cache becomes "Pinned".

I believe it'd be related to pinned tabs. Do you have any pinned tabs?

I don't know about pinning, but: 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.

Thank you for your answer. It helps me to fix the Pinned cache. However, I'd like to know in what case a cache becomes "Pinned".
