I want to create my own Add-on for personal use. In Firefox developer edition is it possible to create and use your own Add-on by disableing the flag: xpinstall.signatures.required.
However, this is not possible with the stable version of Firefox . (except with: about:debugging, but that is not precistant.)
I suggest allowing users to disable xpinstall.signatures.required in the stable version of Firefox .
Optionally: to reduce abuse of this system; allow the user to specify a key in the browser that he has to match in the manifest file of the Add-on(s). However, because of the dificulty of finding the option to install Add-ons using a file in the developer edition; I think that this is totally over due.
