Hi, I guess I'm a noob at this, I download the extension Zip, unrared it....but now I'm not quite sure how to install itwin7, latest FFThanks--Party On Garth! ... Party On Wayne ! Shwing!
In Firefox go to menu item Tools|Add-Ons. Drop down the little gearbox, just to the left of the "Search All Add-ons" box. Select "Install Add-on From File..." and go find the xpi file.
You can also just drag/drop the xpi into the add on manager window.
thanks, works like a charm
