663067 - Non-functional horizontal scroll bar in Add-ons Manager

Status: NEW

(Firefox :: General, defect)

Description

Attachment: Screenshot 1

Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0 - 5b5

When resizing browser while in Add-ons Manager, the horizontal scroll bar becomes useless - see Screenshot 1

Reproducible: always

Steps to reproduce:
 1. Start Firefox
 2. Open Add-ons Manager
 3. Go to Extensions (issue applies for the other panes also, but it's more visible on Extensions)
 4. Resize browser horizontally until a scroll bar appears at the bottom

Actual results:
 - after a certain point, the horizontal scroll bar does no longer function

Expected results:
 - entire window can be scrolled horizontally

Note:
 - issue is also present on the latest nightly, so I suspect it was present for a while
