Why is data being retained in the Firefox Internet cache when I always use Private Browsing ?

OS Windows 7, using Firefox 33.1.1. I have set "Never remember history" so always use Private Browsing mode. I use CCleaner to delete unwanted files from my PC on each reboot, and notice that despite using private browsing mode CCleaner is deleting files every reboot from Firefox's Internet Cache. This morning, for example, there were 203 files with 2805 KB of data deleted by CC Cleaner from the Firefox Internet cache. What data is Firefox storing there from private browsing sessions?

Hi sidb, It is possible to view the cache at about:cache. However everything in private browsing is not saved when Firefox quits.

If you are in private browsing mode then the location for disk cache should be empty and show the same as the memory cache.

Are you sure that this is the disk cache as there is more stored at the location where the disk cache is located?

  • C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\

Note that plugins may always store data on disk in their own cache.
