Update: I've received feedback from AMO, asking me to instead create a self-hosted version of the beta version of uBlock Origin:
Please submit your development builds as self-hosted versions to your original add-on.
So essentially publishing a dev build on AMO is being refused. I will need to read more about self-hosted versions and how (and if) this can be done on GitHub.
I've received an email from Mozilla informing me that starting February 22nd, 2018, the beta channel on AMO will no longer be available for developers to publish beta versions of their extensions.
As per email, those using the beta version of uBO will be automatically moved to the latest release version of uBO when the release version become greater than the last version available in the beta channel.
Given this, the new uBlock Origin beta version is now located at: https://addons.mozilla.org/en-US/firefox/addon/ublock-origin-dev/ (see update above).
Keep in mind this is a distinct extension from uBlock Origin stable on AMO, and this means they can't share settings, and the first time you install that dev build, all the settings/filters/rules will be the default ones. If needed, use the backup/restore feature to transfer settings between both the stable and dev build.
