First tab will not close and address bar in tab does not update.
The first tab and its address bar are not working as expected. I am unable to close the first tab using the close icon on the tab or by selecting close tab from right click menu. I also find that the address bar when displaying the first tab does not display the current web address, only text that has been previously written into the address bar field.

While trying to figure out a solution, I removed my themes and I closed the tabs I could, then clicked on the new tab button, doing so changed my original tab into an (Untitled) tab and created a new (Untitled) tab. I then found I couldn't close either tab, I clicked on new tab again, got a third (Untitled) tab, which again I couldn't close. I then closed Firefox choosing not to save. This appears to have fixed the problem; however I do not know which of the above action(s) resolved it.
I'm having the same problem. I've filed this bug at Bugzilla. (ID 610787)
