Status: NEW

(Firefox :: Tabbed Browser, defect)

Scroll buttons from tab bar are overlapped if you have many app tabs and you restart the browser. After restart if you resize the window (drag the right side of the window to left) and make it smaller you can't see the buttons anymore, they remain somewhere at right.

Steps to reproduce:
1. Minimize the window so that you don't have to create to many app tabs.
2. Create app tabs until the the tab bar of the window shows only app tabs.
3. Close and restart the window.

Expected results:
The scroll buttons should be like before the restart.

Actual results:
The buttons are one over the others like in the screenshot.

Confirmed. Scroll button overlaps with new tab button in the minimized mode after restarting firefox with app tabs.

Seems like we do not handle a long list of app tabs very well. Especially not when the window has been resized and is small enough to not cover all of the open app tabs. In situations like those we loose UI which should not happen. Asking UX for a proposal.
