Re: [Bug-gnuzilla] Addons

I dug into this some more today and noticed this output when running IceCat from the terminal

1569952665143    addons.xpi    WARN    Download of https://addons.mozilla.org/firefox/downloads/file/3413998/librifyjs_sumofusorg-0.1.0-an+fx.xpi?src=""> failed: Error: Cannot find id for addon /tmp/tmp-nym.xpi (resource://gre/modules/addons/XPIInstall.jsm:1544:17) JS Stack trace: address@hidden:1544:17

So that indeed confirms that the missing extension ID is the culprit.

Some people have also mentioned a similar error message in posts about the expired certificate problem that broke *all* Firefox extensions earlier this year (see https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/). However, if I'm understanding correctly, this has been fixed in 60.6.3 so IceCat being based on 60.7.0 should not be affected. Indeed, the extension(s) they offered as a temporary workaround in the post linked above did not seem to help in IceCat. This also doesn't seem related because IceCat appears to be setting xpinstall.signatures.required to false by default which should skip the signature check.

Hi Michael,

I'm facing similar issues with my own extensions and I think I've
tracked it down to a setting in the extension's manifest. Out of my
three extensions, the only one that installs in IceCat from
addons.mozilla.org has this in its manifest:

"browser_specific_settings": {
  "gecko": {
    "id": "...",
    "strict_min_version": "50.0"
  }
}

The other two don't have the ID or minimum version set in their manifest
and they fail to install from addons.mozilla.org.

I downloaded the XPIs for the extensions you listed and none of them
seem to have this settings section either in their manifest.

This guy here describes how one could download the extension's XPI,
modify the manifest, then have Mozilla sign it for self distribution to
finally install it:

That doesn't seem to be a long-term solution though. :/

Best,
Johannes
