Firefox is an important choice to have out in the market. They were at one point the only browser that used its own dll files, not simply piggybacking the stock browser's. That was a distinct feature-
When my 2.1 tablet could not join the ad hoc network in the office, I was told to connect with the alpha of Firefox. I was able to connect through Firefox one time. Then I uninstalled and was able to use tbe stock browser afterwords.
(Had to unload Firefox because the tablet had tooo little space.)
Now that I'm playing with honeycomb tablets I will be happy to give them another shot!
