There is a general support article addressing potential solutions to this issue: [[Warning Unresponsive script - What it means and how to fix it]]. Are you getting the dialog that lists an address? Long addresses have ... in the middle, but it still might be useful to make a note of it. 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 - 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 ---- Regarding Help: * the "?" is on the bottom row of the graphical menu next to the "power" icon which exits Firefox; you access the graphical menu using the menu button with 3 horizontal bars (which some people called the hamburger) * there is a Help menu on the classic menu bar, which is hidden by default; you can activate it temporarily by tapping the Alt key or the F10 function key
