How can I disable signature checking for Firefox add-ons?

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.
