I get the error message "unresponsive script" when I try to open Firefox, and then I can only delete the message by going to Task Manager.
After I downloaded the Firefox update, when I tried to open Firefox I got the error message: "Warning unresponsive script...etc". This happens every time and the choices in the message ("continue" etc) are unresponsive. Further I can't delete the error window without going to Task Manager to end the program. The problem also disabled Internet Explorer which will now simply not load. Google Chrome is working. I assume it relates to the update since the problems (for both Firefox and IE) occurred immediately after the download.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
