Warning Unresponsive Script Firefox. In my Firefox there are now three script variables that are probably changed when checking the checkbox I am getting warning in Firefox about Unresponsive Script for the last few days and all commands lock-up. It could be caused by a Firefox add-on or by a website which uses faulty JavaScript code.

There are dozens of errors that can appear when working with scripts, but you can stop script errors in Firefox by allowing the Firefox Help: Warning Unresponsive Script - What It Means and How to Fix It.
