I am trying to package an add-on that I created with a custom installer for firefox nightly, but the add-on is not being automatically installed with the browser.

I followed the instructions at https://support.mozilla.org/en-US/kb/repackaging-windows-installer and at https://support.mozilla.org/en-US/kb/deploying-firefox-with-extensions, but to no avail.

Any help would be greatly appreciated.

Did you sign the add-on on AMO?

No, but using firefox nightly, I changed the setting xpinstall.signatures.required to false using a preferences file in browser/defaults/preferences and thought that should work. Is that not possible?

Did you make that change in the nightly you were packaging as well?

I can't make any guarantees that will work with nightly.

I would recommend signing the addon on AMO as an unlisted addon.

Yes, I made that change, and when I reloaded it on a new profile, it worked.

But I will sign the addon as unlisted, as you suggested

If you need an "official" version of Firefox that definitely supports unsigned addons, you can use the ESR.

Thank you, that was very helpful
