1325350 - Allow simplified detection of extension updates for notification purposes (chrome.management.onInstalled)

Status: RESOLVED DUPLICATE of bug 1282984

(WebExtensions :: Untriaged, defect)

Description

[Kestrel]

It should be possible to get notifications of extensions being updated which was possible with Addon Update Checker and Update Notifier.

Update Notifier had 161,000 users in 2011 (now 6,000 after breaking in 2012).

Addon Update Checker had 32,000 users in 2013 (now 12,000 users).

This would only require chrome.management.onInstalled which is able to detect extensions being updated.

The ExtensionInfo callback parameter doesn't need to give much information, the extension name would be nice but if that is too much, the event alone would still be useful.
