This type of error is usually caused by an add-on you've installed. It could be anything from an antivirus link scanner like AVG Safe Search, or McAfee Site Advisor, or something similar.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.
