I noticed that CCleaner has a listing for Firefox Hellobeta in "browser plugins" -Firefox. It can be turned on or off. However, when I look at my Firefox addons it is listed nowhere. Any explanations? Thanks.

I had the same problem after deleting Thunderbird. Thunderbird stayed on the CCleaner menu no matter what I tried. Makes no sense to elaborate about what did not work. The only thing that did finally work was to go into "safe mode with networking" and do a search on the local disk (C: in my case) for "thunderbird". Then I deleted the files listed (which had actually been "deleted" already before in normal operation mode. The files are very stubborn.
