Can only open 4 tabs in window. Then + button doesn't work, and New Tab greyed-out in menu.
Running Firefox 7.0.1 on Mac OS X 10.7.1.
Number of tabs that can be opened in a single window is limited. Can't currently open more than four. Clicking the "+" button to the right of open tabs does nothing, and the "New Tab" option in the file menu is greyed out.

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.
