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.
