After discussion of progress on metamask integration items with @jonathansampson, adding this to the 0.20.x milestone.

@kevinlawler Thoughts on this one? Do we presently have an event to hook-into?

[kevinlawler]

The chrome.runtime.* libraries do not follow the same pattern for support that the previous libraries I've enabled have. I have spoken with @bridiver a little bit about this, and it seems like this logic will need to live in C++. For chrome.runtime.*, it looks like roughly half of the calls are currently enabled, some of them with exposed hooks through the JS. Many of the enabled chrome.runtime events live here

$BLB/src/extensions/renderer/resources/messaging.js

Unfortunately, if you search in that file there are no hits for onInstalled, which means it probably doesn't live there. Running chrome.runtime.onInstalled.addListener inside the console for an extension returns without error, but I have yet to verify that the functions passed to it are triggered at the correct time later on.

There are some hits for onInstalled here

$BLB/src/extensions/browser/api/runtime/runtime_api.cc

and this is probably a good place to begin looking to see how much of the code is live or dark.
