User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b5) Gecko/2008032619 Firefox/3.0b5
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b5) Gecko/2008032619 Firefox/3.0b5

If you doubleclick on the left or right tab bar arrows to scroll left or right one window's worth of tabs, you scroll left/right one tab on the first click, then an entire window's worth on the second tab.  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
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.
