PRIVATE BROWSING Button Rated 2 out of 5 stars

Needed for FF 3.5

A quick and easy button to the new
PRIVATE BROWSING function.

Then I'll download this app.

Ta mucho chappies

This review is for a previous version of the add-on (0.1.2). 

i'm happy to add new icons

giving a low rating isn't going to make me add them any faster

and you didn't say which extension so i'd guess this one?

or are you asking me to add a button (my extension just adds icons not buttons or menuitems)?
