I installed and was very excited to start using it.
It froze the phone up on the first webpage load. Had to battery pull. I will be uninstalling.
Apparently Firefox still thinks that they're developing a Desktop browser here, because this thing is SLOW.
Come on Mozilla. Either push out a quality product, or don't push one out at all.
I'm running this on a Droid 2, and it didn't freeze. But it's still a terrible browser. The first thing I did was go to Facebook and log in. Every time I pressed a key (using the physical keyboard) It would zoom in and out. It got extremely annoying. Pressing the menu key doesn't do anything except show the page's encryption. Pressing a key doesn't automatically start a search. When using the onscreen keyboard for searching, the search button is extremely small and has no text on it. And yes, it's slow.
Ridiculously slow, all pages were unreadable, especially when zooming in. absolutely awful, and its not like there were any unique features to it, even if it did work.
