891365 - cannot install facebook from french facebook pages

Status: RESOLVED WONTFIX

(Firefox Graveyard :: SocialAPI: Providers, defect)

Description

[Florian Quèze [:florian]]

I was doing some testing with a nightly with a new profile and needed to enable Facebook messenger. I typed "facebook messenger firefox" in Google.

The first result was:
https://fr-fr.facebook.com/about/messenger-for-firefox

Clicking on the "Activer" (activate) button on this page just disables the button and nothing else seem to happen.

The browser console shows:
[16:40:18.951] [Exception... "'Error: Cannot install provider without manifest data' when calling method: [nsIRunnable::run]"  nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)"  location: "native frame :: <unknown filename> :: <TOP_LEVEL> :: line 0"  data: no]

The issue doesn't happen if I use https://www.facebook.com/about/messenger-for-firefox instead.

This is caused by a combination of two items.

- we check the install origin (fr-fr.facebook.com) against the origins of builtin prefs, which doesn't recognize the builtin pref since the builtin is www.facebook.com.
- facebook does not send the manifest in the activation event (they are the only provider using the old mechanism)

We can probably get a fix from facebook for the second item, but I think the first is still an issue we should see if we can somehow address.
