Hi

My Firefox browser does not load when I click on the icon.
Instead a box pops out with the following message:

Warning :Unresponsive script
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: chrome://tavgp/content/libs/include.js:301
Continue Stop Script

I am given the option of either to Continue or to Stop Script.When I choose the latter the browser will launch.
This box keeps popping out on and off whenever I click on something and it slows down my computer.
I could not trace the file by this name.
I tried Disk cleaning,deleting incompatible Firefox plug-ins and the Registry Cleaner to fix issues but these have not worked.My mouse has become unresponsive to clicks

I would appreciate if someone could fix this issue
Thank you in advance
