This is a similar problem so I didn't start a new thread.
I was having a problem with CCleaner not cleaning all my cookies when I upgraded to Firefox v2.0.0.5. It cleared some but not all.
I uninstalled and went back to v2.0.04, now CCleaner cleans all my cookies just fine.
I rely on CCleaner to clean all cookies at the end of the day so I'll be logged out of all boards that I'm a member of.
IE7, Opera and Firefox. Until I updated FF to v2.0.0.5!
That's when the problem started!
I even tried other cache cleaners.
ATF-Cleaner was the only one that worked but I had to clean each browser one at a time!
CCleaner cleans the cache in all 3 browsers in one click.
Others here with the same problem.

Cookies not cleaned seems like they are IPB related forums.
If I need to start a new post just let me know.
