Unknown Mozilla dev addon "Looking Glass 1.0.3" on browser

Many people seem to be shocked because Mozilla installed an add-on automatically. In my opinion, it doesn't really matter since the code is coming from Mozilla - they're building the whole browser, so they could introduce functionality anywhere. If someone distrusts their add-ons, why trust their browser at all?

The main question is what behavior is being introduced. I haven't researched deeply, but apparently the add-on does nothing until the user opts-in on studies.

It adds some css to a list of words:

Only if the preference extensions.pug.lookingglass is changed from the default of false.

I haven't figured out how that setting is exposed yet. Maybe they expect people to go to about:config and change it? Is there video footage suggesting that in the TV show?

From reading the source, that setting is not exposed anywhere; about:config seems to be the only way to turn it on.

From reading the commit history, it looks like it's still under active development.
