Many sites will show errors in the error console but they can be ignored. The errors you mentioned in the first post for example can be ignored.

If you find Firefox is running slowly, check to see if an add-on is causing problems. To do that start Firefox in safe mode Firefox safe mode, this will disable add-ons and can be used to see if one is causing problems. If it works OK in safe mode, follow the procedure in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article.
