Few days ago Mozilla launched Mac and Linux versions of Prism. What’s Prism (WebRunner) again? It’s a stripped down version of Firefox that essentially lets you load a single web page at a time. No tabs, no useful URL or navigation buttons. But Prism can come in handy if you like to keep a single web site like Gmail open all day, since it uses fewer resources than Firefox.
As it is only 0.8 version, expect to encounter bugs such as F11 failing to go into full-screen mode and Prism not being able to notice that Flash is installed. All in all, not a bad release but there’s still lots work to be done.
