Try resetting the Extension Manager. With Firefox closed, delete the following files in your Profile folder':
extensions.cache
extensions.ini
extensions.rdf
and
compatibility.ini
They'll be re-created when you open Firefox.

Making sure Firefox closed:

Profile location:

You may need to show hidden files to locate your profile:
