Sorry, it was my fault. In fullscreen mode, when you right click on the navigation cum tab bar, there is an option to check/uncheck whether you want to hide the toolbars or not. It seems that by mistake i unchecked it.
As for Chris's question, i am using firefox 13.0.1 and the fullscreen feature is working for both tabs-on-top and tabs-on-bottom. As for now, this problem can be marked as solved. ** Changed in: firefox (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010334 Title: fullscreen feature is not working after today's update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1010334/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
