wine users - Mar 2011 - Mozilla Firefox New Tab Problem

The last two day i have a problem with Firefox new tab. When i press
the button for a new tab nothing happens. Can anyone help?

Thanks

Question: why do you use the Windows version of Firefox? Dogfooding?

What do you suggest?

The Linux (or Mac?) native version of Firefox.

Can i have Windows and Linux in the same pc?

I have never use Linux before but im interested to start.

--- The problem with firefox is ok. I downloaded Firefox 4
and works fine
