The add-on manager's menu button doesn't work for me.
Try pressing it in the Firefox menu, no dice. Going into Options, and finding 'manage add-ons' in there works, but opens a new window. I usually drag the only tab of this new window into the existing window to work, but the issue stands.

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.
