FF 12.0 tabs no longer draggable since updating from 11.0
Win 7 x64 Can't find any options in either FF or any of the Tab add-ons installed that could affect the tabs ability to be dragged to a new position or not. I've since restarted the computer numerous times. Can't drag tabs even to the desktop to create a new window. WHAT'S UP ?!?!
EDIT: Haven't tried yet to 'upgrade' my PortableApps.com version to 12.0 (use the same add-ons on both installed/portable versions)

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
