This issue is caused by the Skype extension for Firefox.


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).

As suggested I started FF in Safe Mode and I did not get the error. What can I do now to trace which extension is causing this error?

Also can anyone give me a email address for Skype as I cannot find one. So that I can contact them and ask them, if they have an update to fix the problem

Yes, I went in and disabled Skype and then powered down the system and I think that this has resolved the problem as when I went back it. I do not know have the error.

Many thanks
