I have even reinstall firefox but the same result message appear.

This is caused by an add-on, see troubleshooting extensions and themes to identify which one.

I see you have the Ask toolbar, that toolbar has caused this error message for some people.

I have tried as per your suggestion and removing the Ask toolbar and have solved my problem. Thanks for the advice.
