Delete Cache Trash


My Firefox profile has a folder with the file name Cache.Trash16149. It is 2.7GB and has over 640 thousand files in it. I cleared the cache and a second Cache.Trash folder was created with the latest round of deleted files.

Why is Firefox keeping all the deleted cache files in my profile? How do I get rid of them? How do I keep Firefox from keeping them?

I am running FF 17.0.1 on a 64 bit Win7 computer.

Firefox moves the current cache folder to a cash trash folder if Firefox hasn't updated the cache index files properly on the previous close down (_CACHE_CLEAN_ file).

Make sure that Firefox closes properly and that there isn't a hanging Firefox or plugin-container process left in the task manager.

Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.

You can remove the trash folder(s) if Firefox hasn't done this automatically on a next start.
