Wow if ad blockers can work does that mean Firefox injects this advert?

Its not just and overlay but code added to the webpage?

I'm awe struck at the stupidity of this idea.

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

>>psychp+(OP)
Unlikely. My guess is that the ad code runs in the context of the browser itself or some newly created context, rather than of the page you were reading before, but whatever fetch() or similar call it makes to load the ad goes through a subsystem that is affected by ad blockers.

Put another way, when you allow ublock or whatever you're using permission to intercept requests for ALL pages, that includes the "page" that mozilla is using to serve this ad.

Further evidence in favour of this hypothesis is that the ad can temporarily disable the rest of the firefox UI until you deal with it, which normal pages certainly can't do.

>>psychp+(OP)
I doubt it was injected into pages. The screenshots shows the top chrome dimmed. I suppose people conflated not being randomly selected to get the ad with an ad blocker blocking the ad.

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.
