This leaves the tab that was originally one tab off-screen to the right/left now one tab off-screen to the left/right, rather than being the left/right-most tab as it should be. Reproducible: Always Steps to Reproduce: 1.Have enough tabs open to have several windows worth 2.double-click left or right tab bar arrow 3. Actual Results: tabs scroll one more than a window's worth left or right Expected Results: tabs should scroll one window's worth left or right. This is not a new problem with beta 5

Can confirm this bug in recent Firefox 11 (Win7). This is a real nasty bug. The tab-list is scrolled at least one tab to far by doubleclick the scrollbar arrows. This bug is insided since version 3 or earlier. Please, please fix this!! It is independent on the screen size. If you can't verify this: My settings are no menu, navigation tabs visible, tabs on top.
