I would like to test my unreleased addon for a longer time in Firefox for Android. But I only know how to load it as a temporary addon.
How can I load it permanently on the device to test it?
I think you will have to release it.
But you can mark it as Experimental - in the “Edit Product Page”:
I think experimental addons are excluded from the search results so nobody except you should be able to find it.
I assume you know about this bug to allow nightly builds to load unlisted add-ons again. That’d help your issue, right?
Vote if you care.
