forward and back arrows do not work on 7.0 beta, they are grayed out
The forward and back arrows on 7.0 beta are grayed out and do not work. Same issue on other earlier versions.
I have done complete uninstall and then reinstalled, though same problem persist.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions 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.
