What is the full error message? When do you get it? One web site, several, many?

What address does the dialog list? For example: * addresses starting with the name of the site usually are features/functions of the page * addresses from other sites often (but not always) are advertising networks or trackers - using an ad blocking extension can help address issues with slow or dysfunctional ad network scripts * addresses starting with chrome:// usually are part of Firefox or of an extension you installed - the Skype extension sometimes causes this problem, for example ---- We have a general support article addressing potential solutions to this issue: [[Warning Unresponsive script - What it means and how to fix it]]. Another common cause of unresponsive script errors on Windows 7-10 is the protected mode feature of the Flash player plugin. That feature has security benefits, but seems to have serious compatibility issues on some systems. You can disable it using the Add-ons page. Either: * Ctrl+Shift+a * "3-bar" menu button (or Tools menu) > Add-ons In the left column, click Plugins. On the right side, find "Shockwave Flash" and click the More link. Then ''uncheck'' the box for "Enable Adobe Flash protected mode" and try that for a day to see whether it helps.
