This extension does not keep the "checking compatibility" pop-up window from appearing. It keeps add-ons designed for older versions of Firefox from being automatically disabled. Many of the reviews here seem to reflect that the description for this Add-on needs to be written in less technical terms, but the extension does work quite well.
