No it's not blocked by ad blockers, since this was not injected in pages but part of the browser UI (the "chrome").

  I wonder why I have not seen the advert popup then. I run Firefox daily for 8 to 10 hours and I've not seen it once... Something must be blocking it for me.

    Looks like that was an experiment targeted to a subset of the user base, and you were just not in the pool.

    As far as I can tell, it was run for a few hours and required Firefox to be left open and idle for 20 minutes before it appeared.
