      Yup. I just got one for some new Firefox feature. And Pocket has been a thing for a while, which is basically an ad engine.

      I still use Firefox because I can easily disable that nonsense. I’m mostly here for engine diversity, so once a reasonable competitor exists (LadyBird? Servo?), I’ll bail.
