Do you still get that error message if you start in Safe Mode? https://support.mozilla.com/en-US/kb/Safe+Mode Or with a new, clean profile? https://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile
Component: General → Add-ons Manager
Product: Firefox → Toolkit

Sounds like you have some extension installed that is trying to use things not present in Firefox 4.
Component: Add-ons Manager → Extension Compatibility
Product: Toolkit → Firefox
QA Contact: add-ons.manager → extension.compatibility
