Status: RESOLVED DUPLICATE of bug 649654

(Firefox :: Tabbed Browser, enhancement)

Deleting tabs in succession doesn't work when scroll buttons are present in the tab strip.

Step to reproduce:

1. Start Firefox and open some blank tabs until the scroll buttons appear in the tab strip.
2. Select first tab from the strip and begin closing the tabs from the "x" button until the scroll buttons disappear. 

Actual results:
When the scroll buttons disappear, the whole strip is resized leaving the "x" button of the tab not focused by the mouse cursor anymore, meaning that you have to move the mouse in order to continue closing the tabs. 

Expected results:
You should be able to delete all the tabs continuously. 

Not resizing the tabs until you move the mouse off the tabbar is a great thing and in my opinion the scroll buttons must have the same behavior. The buttons must disappear only when you move the mouse off the tabstrip.

Ack, copied wrong bug number. My bad.

This is not a duplicate because it's not the same behavior.
The tabs are not resized when you delete them but the tab bar is. See actual results from description.
IMO this is a bug. The tabs are not resized for one reason so they can be all closed in succession. I found that they are not closing as expected, so this is a bug.

I read the description. It is a duplicate. The scroll buttons themselves do not have to remain. Instead, the space they take up should persist until mouseout. When I land the fix for bug 649654, you'll see what I mean.

A dependency might be a clearer way to indicate that; "handle more gracefully" and "feature broken" aren't really the same at all. Or maybe bug 649654 just needs a better summary.
