Does not clean Firefox cache if it is not in the default folder.
For example in M:\Cache\ not in C:\Documents and Settings\...\Local Settings\Application Data\Mozilla\Firefox\Profiles\xxx.default\Cache\

It is NOT a BUG.
CCleaner does not bother with obscure locations, it uses defaults.
My Firefox caches are on a secondary drive - ultra obscure,
but CCleaner does clean them because I replaced the correct default folder with a Junction point that reroutes to my caches.
You can clean the Firefox cache folder by adding it to the Option, Include list; and enabling the Advanced, Custom File and Folders; option.
Just be careful not to delete too much.
much easier to use custom location feature (works for chrome and firefox)
