I have tried doing that in super-dev mode at least .At that time i was able to see those tabs which were not after firefox update
But i get the following popup while opening firefox:
ERROR: Possible problem with your *.gwt.xml module file.
The compile time user.agent value (safari) does not match the runtime user.agent value (gecko1_8). Expect more errors.
I guess we can get rid of the popup.But my concern is by generating only chrome permutations
1)Will all the functionalities of UI work in firefox(UI is pretty complex and large .I may have to test thoroughly to conclude )
2)Even if it works in latest firefox, will it guarantee that it will work in older version as well(If user is using older version of firefox)
