My b2evolution Version: 3.3

Hi, with the kind help of sam2kb I have got the feature section of my blog working but, can anybody please tell me how to cut and paste with Firefox, when I try I get a message saying:

Copy/Cut/Paste is not available in Mozilla and Firefox.
Do you want more information about this issue?

I click ok and follow the instructions by adding the extra lines to profile but it still does not work.

I use Firefox because when I use IE I can not logoff from the admin page.
:'(
