Anyone else having the same bug I'm having?
When using the Mozilla engine in the new browser and the browser is in
full-screen mode with the toolbar hidden, tapping into a text entry field on
any web page in the browser results in the keyboard popping up for a second and
then going back into hidden state.
When browser is NOT in full screen mode the keyboard shows up fine when tapping
in a test entry field.
When browser is in full screen mode AND the toolbar is NOT hidden the keyboard
works just fine and stays up when tapping in a text entry field.

If you are, please add to the bug in the link above.
