[Feature Request] Firefox now allows unsigned, unlisted addons

[YYYYY-yyyyyy]

Unlike Chrome, Firefox does not allow extensions meant for testing to be hosted in the marketplace. You will have to download a desired version and side-load it yourself. You only need to do this once and will get updates automatically.

Would it be possible to sign the releases (on github) with (web-ext-sign)[https://extensionworkshop.com/documentation/develop/web-ext-command-reference/#web-ext-sign] ? right now i need to use the dev version of firefox which is less than ideal.
