The error message when I add a bookmark
When I add a bookmark, a window appears with the message: unload: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIObserverService.removeObserver]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://trustchecker/content/trustchecker.js :: <TOP_LEVEL> :: line 991" data: no]

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).
- Don't make any changes on the Safe mode start window.

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