1614295 - Notify GeckoView embedder apps of new temporary extensions installed through the Remote Debugging Server

Status: RESOLVED FIXED

(GeckoView :: Extensions, enhancement, P1)

Description

[Luca Greco [:rpl] [:luca] [:lgreco]]

When an extension is installed temporarily into a GeckoView-based application (e.g. Fenix) through the RemoteDebugging Server (e.g. by web-ext run, a vscode webextensions plugin or from about:debugging), the embedder app isn't currently being notified of the newly installed extension, and so it doesn't receive the GeckoView representation of the installed extension and some parts of the extension UI, like pageAction/browserAction and options pages, would not be created.

See mozilla/web-ext/pull/1834 for the initial Fenix support in web-ext run (which is also an easy way to reproduce this issue)

Attachment: Bug 1614295 - Provide a way for apps to know when an extension is installed.

This patch adds a onExtensionListUpdated method to DebuggerDelegate which
is called whenever devtools install a new extension.

This method provides an opportunity for apps to refresh the list of installed
extensions and sets appropriate delegates so that the new extension is
correctly recognized.
