Publish to an external add-on database / self-sign

[Istador]

This add-on can't be added to AMO because they won't sign nor accept legacy add-ons anymore. They will drop all XPI files from there servers in October 2018, causing problems for other Firefox forks that use AMO for extensions.

Likewise, Thunderbird's add-on page (ATN?) accepts legacy add-ons, but won't sign nor accept add-ons that are for Firefox and Thunderbird.

Hopefully, Waterfox's legacy extensions database (BrowserWorks/Waterfox#303) will someday allow signing and submitting new add-ons.

Palemoon is hosting their own add-on database and is open for submissions, but this add-on wouldn't enrich it in any way, because they forked away before Firefox 43 changed the Search Bar for the worse.

How is IceCat's and Bisilisk's stand on legacy add-ons and hosting them?

There should be a free and independent extensions database that targets all browsers.
How difficult would it by to host that or develop a distributed solution?

Another thing to improve the current situation at least for my add-on, would be for me to self-sign the XPI release files. I haven't come around to install NSS on Ubuntu or Debian yet.

From The Waterfox Blog | Waterfox, Its Legacy and Looking to the Future (2018-04-28):

• Independent add-on store …

I imagine that this will be separate from the database that is (to be) used for Waterfox integration with the Classic Add-ons Archive.

Waterfox aside, JustOff/ca-archive#9 exemplifies a request for one-off addition to the archive.
