This is the right answer, and more people (especially technical people like frequent HN) should be pointing this out.

"What ads? Oh you must be running Chrome" needs to be the common refrain.

Really hope this ends up being a surprising tide shift. Firefox has dipped really hard in marketshare, but there's no reason it can't start to gain again/grow steadily.

It's really too bad the Firefox tent wasn't big enough for all the alternative browsers that exist (though of course they're not scratching the surface of real usage either). I skipped the whole Arc wave and I'm glad I did -- it's a distraction from Firefox.
