Building my presentation for the FL Drupal Camp I was stuck - neither Firefox nor Safari would let me do a full-screen browser display so the audience was going to be stuck seeing my title bar, browser window border, tool bar, etc - not terribly good for a presentation. A bit of searching later I discovered the perfect solution - PlainView.
As a typical sign that a major software product is ready for launch, mozilla.com is down and the release of Firefox 3 had been rumored for Any Day Now, so I guess half of the known universe tried to check all at once and took out their servers.
