This means that it is no longer possible to install add-ons from third-party sources in Firefox, or old add-ons, if they have not been signed. Unsigned add-ons are all add-ons that have not been submitted to Mozilla for signing.įirefox displays "This add-on could not be installed because it has not been verified" when you try to install an unsigned add-on in Stable or Beta versions of the browser.
