I've been using CCleaner for a few months now and I have updated to the latest version.
Ever since using it, the same problem has occured, something weird happens to my web browser pages after running the cleaner; I have to reboot to correct it. Nowadays, I run CCleaner just before shutting down for the night so it doesn't impact upon me, but I thought you might like to know.
I am enclosing two shots, before and after for your comparison and hopefully a fix to this bug (is it a Firefox thing?).
