There is no way around this other than switching to another Firefox channel that still offers a switch to turn the functionality off.įirefox Developer, Nightly, ESR and unbranded builds fall in that category.

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. This blocks them from installing unsigned add-ons in Firefox. Firefox will continue to function on those platforms, but won't receive new features or security updates anymore.įirefox Stable and Beta users may no longer disable add-on signing in their versions of the browser.
