User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120420145725

Steps to reproduce:

No idea, it happened after leaving that computer on for some days.

Browser has 15 pinned tabs, and 27 normal tabs.

OS: Mac OS X 10.7.3.


Actual results:

The tab bar stopped "scrolling" to show the new page's tab when opening a new tab (either from a page or from a third party application).

The content is there, but when you look at the tab bar you don't see the tab, not until you scroll manually with the arrow widget.

The page's title does appear and can be selected in the dropdown menu of opened tabs.
(I don't know if it is relevant, but since I noticed the bug, the new pages' titles in the dropdown are on a different background colour than those of previously opened tabs.)


Expected results:

The tab bar should have automatically scrolled to the right to show the new tab's title.
