Since version 42, Firefox, by default, refuses to install unsigned add-ons. How do I disable this verification?

It is only possible to disable addons verification in Nightly and Developer channel. In other words it is not possible in Beta versions and standard releases.

  1. Go to about:config (enter it into address bar)
  2. Set xpinstall.signatures.required to false.
