menus.ContextType = history

I’d like to be able to add a context menu for the history view.
According to https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/menus/ContextType

There is no such context.

What is the proper way to request this? Thanks

After like 45 minutes of Google I finally found https://wiki.mozilla.org/WebExtensions/NewAPIs just to face "User account creation has been restricted. "

Seriously? To me as a newbie it feels more and more like Mozilla intends to discourage new developers.

(and: why can this magical Mozialla SSO not be used for bugzilla, but Github can?)
