  7. Click OK and restart Firefox.

Disable Extensions

In the Unresponsive Script Error you’ll come to know the name of the extension which is taking longer time to load. Disable concerning extension to fix your problem. Names of some extensions that usually cause this problem are- Avast WebPro and Ad-Block.

  2. Select Tools and then Extensions.
  3. Either disable or remove unresponsive extension. To disable it, uncheck Enable checkbox. Or to uninstall it, click Remove button.
