What happened? Rated 5 out of 5 stars
I've been using Full Screen for sometime, and I like it just fine. I use it on two computers. Now. on one of the computers, I can't install it, getting the error message that it is incompatible with Firefox v 3.0.1. On the other computer, though, it works just fine. Go figure.
An update. Full Screen installed and worked fine after I uninstalled Foxmarks. I didn't try reinstalling Foxmarks to see what would happen.
