There you can change the options in `about:config` (these options do not work in the main version of Firefox)
`
xpinstall.whitelist.required on false
xpinstall.signatures.required on false
extensions.legacy.enabled on true
`
And then every extension works, even experimental and a large part of those based on the former API.
In principle, the Firefox Unbranded version should be the most promoted because it has fewer restrictions on extensions. Even such a version with default options set in `about:config` should exist, and with a larger extension base than AMO.
