Thanks for the great article, which helped me troubleshoot the problem down to the PhonePower add-on.
If you already installed the PhonePower add-on you can resolve the issue by following these two steps:
- Disable the extension add-on.
- In the FireFox profile folder delete the following line in extensions.ini:
- C:\Program Files (x86)\PhonePower\PhonePowerClick2Dial\FireFox
Cheers!
PS - This issue really reminded me just how much I rely on NoScript everyday for a safer, more pleasant web browsing experience. I've decided to make another donation. Thanks again!
