Though Firefox shares a lot of WebExtensions code with Chromium,
these platforms have their own specific code paths, for various
reasons.
The reorganization here makes it clear that Chromium platform is
just one flavor of WebExtensions, and as such all Chromium-specific
code paths should no longer be automatically pulled by other
platforms where these code paths are not needed.
Given that the filepath of many files changed, here is the
parent commit to quickly browse back to the previous directory
