I receive this message after upgrading to 7.0.1 : load: TypeError: Components.classes['@checkpoint.com/XPCOMTrustCheckerMozilla/TrustCheckerMozilla;1'] is undefined

The same message apears, even if I try to open a widget tab on my blogger blog, and every time that a Javascript is needed to work.

Chosen solution

Try Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems. Since Checkpoint is in the error message, start by disabling any ZoneAlarm add-ons in your Firefox Add-ons Manager.

Dear Alice, Zone Alarm was in deed the problem, and your answer was really helpful. The message, after restart the browser is disappeared. Thank you very very much Alice
