Fx 22.0 problem Rated 4 out of 5 stars

Excellent extension but unfortunately stopped working after fx had been updated to v.22.0 . Can it be fixed in any way?
Update 1.
It just does nothing. The tab does not close, no cookies nor history entries are removed.Fx 22.0 , Ubuntu 12.04 32bit
Update 2.
Fx 22b6 - behaviour as described above, but when I open a new empty tab it can be closed by Close'n forget.

This review is for a previous version of the add-on ( 

Details, please ?


I'm sorry to see that you have problem with C'nF. I use it with Firefox Aurora 23.0a2, without any visible problem. Can you give me some details to help me diagnose and try to fix the problem? Thanks in advance.
