Hi Cyberkagami,

I noticed in your system details that you're testing out Firefox Nightly (currently version 14.0) and you're in-fact running the latest version. There is presently no tablet oriented interface available on the 'native' version of Firefox for Android as all the mobile developers have been directly focusing on making a great phone experience foremost for the new product. There are plans to create a tablet interface within the near future (there are mockups of the user-interfaces on Bugzilla bugs) time-frame; it is simply just not available yet. Stay tuned.

To test the tablet interface, you can either get the beta version from here:

or download the tablet nightly build here:
