Caused by an add-on related to that trustchecker chrome:// address.

Disable security add-ons until you find the culprit. Start with Ghostery.

Or maybe ZoneAlarm

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

For me the solution was to go into add-ons manager, click Extensions and disable Zonealarm Security Engine.
