I'm having trouble with Ccleaner and the Mozilla Firefox caché. Despiste unmarking all options to clean Firefox that Cclenaer has and adding the locations were as far as I know the caché is stored to the excluded files (C:\Users\'user name'\AppData\Local\Temp\acro_rd_dir), when executing Cclenar it is still deleting the firefox cache and I don't know why. (in addition, it seems its only affection to the caché storage maybe, like pages that store information in the caché, cause any other page is running well with all my accounts in).
I use Windows 8.1 on this computer and in my Windows 7 laptop only by unmarking all Firefox options is enough.
again, whatever \local\temp\mozilla-temp-files\ is used for, it's not for Firefox cache.
ALL Firefox data is kept in either C:\Users\<your user>\AppData\Local\Mozilla\Firefox\Profiles or C:\Users\<your user>\AppData\Roaming\Mozilla\Firefox\Profiles (this is the main one).
So adding an EXCLUDE of a folder from that second location will be part of your solution.
I'm sorry I can't delve any deeper than that, but I only use Firefox in private mode so don't have to worry about this sort of stuff.
So just to be clear, in CC, Applications tab, when you untick Internet Cache under Firefox, it still gets cleaned?
Yes, I have this option unticked. All firefox options to tick are unticked.
I've added the files that you mention and executed CCleaner after, but it does not work. I was worried because I do not known why and then I've started to think that the problem maybe was not Firefox but Adobe Flash Player.
Then I add the main files (like from you say, from AppData) and it works!
