Somehow I missed this. I think you were quicker than Lifehacker on this.

Works fine as new install, upgrading from 2.0.x shows XUL failure..

As always, support issues go in the forums, not as comments on a news story.

Sometimes, the impossible can become possible, if you're awesome!

And I really like the new features/look etc.

I have tried this on the library computers a dozen times. Though it starts up with a nice splash screen (love the artwork by the way), it either immediately fails and crashes, or it just won't connect to the net (even after playing with setting). However, it will run mysteriously well on a friends Win98 machine and Vista machine. Also runs unusually well through Wine on Debian Etch, Ubuntu Feisty, and Knoppix, but nothing else in the Linux department. Will continue to test as best I can on some of my friends other computers. I like testing beta and experimental software, especially when it's not my computer!

Linux: full pockets, super fast computer, endless software, endless customization, endless potential
