WebExtension fails to install only on ubuntu packaged firefox

[Marius J.]

Hi,

I have recently developed a WebExtension ( https://addons.mozilla.org/en-US/firefox/addon/surligneur/ ) but the installation from AMO freezes on a **ubuntu packaged firefox**. The download starts but the process freezes on the "Downloading and verifying addon" step (even on a clean profile and/or a clean install). In the browser console I get the following error :

A promise chain failed to handle a rejection. Did you forget to '.catch', or did you forget to 'return'?

Please note that :
- I'm using firefox 49 on ubuntu 16.04.1
- Installing the same extension on a Windows system or a Ubuntu system with a firefox directly downloaded from https://www.mozilla.org/en-US/firefox/all/#en-US works correctly.
- Load the addon through the about:debugging page works correctly too.

Best,

Marius

Status changed to 'Confirmed' because the bug affects multiple users.

[Nate Wiebe (natew)]

I get the same issue with an unlisted WebExtension. Works fine on Windows, or downloading Firefox from their site. It's only affecting Firefox installed from the repos.

[paulgreg (paul-gregory)]

Same bug when trying to install my 2 extensions in Firefox 49 on Ubuntu 16.04.1 :
- https://addons.mozilla.org/en-US/firefox/addon/rsstodolist/
- https://addons.mozilla.org/en-US/firefox/addon/uniquepasswordbuilder-addon/

Loading extension from debug page works.
Installing extensions on Firefox Developer Edition (https://www.mozilla.org/fr/firefox/developer/) works.

Here the console trace when trying to install one of those extension :

I see exactly the same problem when trying to install an extension developed in our research project (http://www.hiit.fi/g/reknow/software/dime_webextension-0.42-an+fx.xpi). It works fine with the mozilla.org version of Firefox (I tested both 49.0 and 49.0.2).

[Pim van den Berg (pommib)]

I've been hitting exactly the same problem on Debian 8 running Firefox 49.0-5~bpo80+1 from https://mozilla.debian.net/. The issue seems to be solved in Firefox 50.0~b11-1~bpo80+1.

Further to comment #6 and upstream bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1315501
issue resolved with Firefox 50, released on 2016-11-15
after which reports of problems ceased.
