Winifred, Thank you for your question, please try the following to start Firefox:

Diagnose Firefox issues using Troubleshoot Mode Shift+click Firefox to start Firefox in Safe Mode. If the error still appears its a corrupt extension.
Back up and restore information in Firefox profiles
Then start Firefox with Profile Manager: Profile Manager - Create, remove or switch Firefox profiles and create a new profile.

If creating a new profile gives an error, consider removing the extension folder in the profile or making a back up of the profile and reinstalling.
