I think the GP is referring to not being able to install non-signed add-ons in non-developer versions of Firefox.

  Yes. You have to have mozilla sign your add-ons after every little edit you make or use the beta/dev with bugs.

  I don't know, my non-dev version has an "install addon from file" menu item.

    Are you sure Firefox doesnt check the signature if you use that menu item?
    • StavrosK 8y ago
      I'm pretty sure, as I haven't signed my extensions before loading them.
