uninstall Firefox.

go to and redownload and install. should work.


Thanks, Experts.
I will try deactivating all AddOns and then if still necessary, uninstall/re-install.
Will revert with final results.


I have now tried de-activating all Addons and Extensions.
So far, there has not been a recurrence.
I guess I will just have to turn back on one or two at a time to finally corner the one causing the problem.
Not a very elegant way of trouble-shooting. But I guess it is the only practical way if no sense can be made of the error message.
Thanks, Experts for your help.
