Aurora 23.0a2 2013-05-15/ Nightly 24.0a1 2013-05-15 HTC Desire Z (Android 2.3.3) / Samsung Galaxy Nexus (Android 4.1.1) Steps to reproduce: 1) Go to google.com, long tap on the search field and add a search engine 2) Repeat step 1 until the about:addons becomes scrollable 3) Go to about:addons and scroll the page to hide the URL bar 4) Uninstall the last search-engine in the list and then try to scroll the page Expected results: When the page becomes smaller then the screen size the URL bar is redisplayed Actual results: If when disabling one addon the page changes between being longer and shorter then the screen size the URL bar can't be accessed anymore until doing a device rotation. On Nightly the first tab opened after this does not increase the tab count but this issue is not reproducible on Aurora - please observe the tab count in the screen video capture Notes: Screen video capture: http://youtu.be/fRbesIUD4HM

I can reproduce this issue on Samsung Galaxy Tab (Android 4.0.4) using the URL: http://neave.com/tic-tac-toe
