1946564 - Invalidate the about:home startup cache when the New Tab built-in addon detects a pending update

Status: RESOLVED FIXED

(Firefox :: New Tab Page, task, P3)

Description

[Mike Conley (:mconley) (:⚙️)]

The New Tab built-in add-on will not update at runtime. Instead, pending updates will be applied after a restart. We need to ensure that any pre-existing about:home cache is also blown away when an update download is detected (prior to restarting), and prevent any further caching until the next restart.

This also makes it so that we remove the shutdown blocker if we uninit.
