I love Cookie Monster and have used it for years. Now using ver 3.47.

I just upgraded to Firefox 6.0, and when I shut it down and try to use Cookie Monster, I get the message “Can’t find Firefox cookies. Be sure your browser is shut down.” or words to that effect.

Is there a later version of CM that I could install over the old one? Would that fix the problem? I can’t seem to find it, but my brain ain’t working so good today.

No idea, but a working alternative is CCleaner.
