Hello there, newcomer here. I'm not sure if this is a bug or not but I recently updated to the latest version of Firefox (version 55) and notice that my favicons or site icons keeps getting deleted when I use CCleaner, which never happened before, at least not with older versions of Firefox. I've pinned the culprit down to the 'Internet History' checkbox in CCleaner, but what I'd like to know is if this is normal, why do I have to clean my favicons just to delete internet history for Firefox now when it worked well before without clearing my favicons?   Right now I clean the files manually because it takes a long time to restore the favicons for my bookmarks which I use to identify site from site because I don't use names just icons in the bookmark toolbar in Firefox and it is somewhat annoying to have to redo all my bookmarks every time I use CCleaner to clear history.   Regards WebHD.
