Generally speaking it is more likely that an extension is the cause if you encounter the error on several different websites while a warning on the same website points to a faulty JavaScript on that website instead. The last error message there should hint at the cause of the error. Users need to stop the script and access the Firefox Error Console using the shortcut Ctrl-Shift-J or with a click on Firefox > Web Developer > Error Console in the menu. Also, oddly, when I open the page using selenium manually it. When I open the page using Firefox without Selenium, I get no errors. The problem is, when opening a page using Selenium, I get numerous 'Unresponsive Script' pop ups, referencing varying scripts. It's actually pretty easy to discover the cause for the warning message. This question has been asked before, but the answer given does not seem to work for me. It could be caused by a Firefox add-on or by a website which uses faulty JavaScript code. There are two possible causes for the error. Follow the below steps to increase the script execution time in Firefox browser. The strange thing was that the website seemed to have loaded completely and that the warning was displayed despite of this. By increasing the script execution time limit, you can allow the script in the web page to run little longer and reduce the unresponsive script warning. That's a pretty vague warning and I was puzzled at first about the cause of it.

I have been encountering a warning in Firefox lately which notified me the that a script on the current website was unresponsive asking me if I wanted to stop or continue.
