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:

i'm on nightly and the default was to opt me in. that's some shady shit. i'm pissed.

mozilla is rapidly burning through over a decade of hard-earned trust and goodwill. i install firefox on other people's machines. i'm not a good user to piss off.

am i gonna have to wait for servo to mature and make an unmozillad servo? what a sad reality that would be.

this is not the browser we were looking for.

if you're on Nightly, this is literally what you signed up for: all the experimental settings and all new functionality turned on by default so that you can be part of the test bed of users and devs that can report back to the larger developer community through Bugzilla when things aren't working the way they should be. Complaining about the fact that Nightly did exactly what it's supposed to is kind of ridiculous.
