We’re in the paradox that it is possible to claim there is no ad on a browser because you don’t look at them when they appear. Similarly, people who are satisfied with a government stance will see no problem in violently repressing opposition. Defects only appear when you are on the other side.

But they do appear, and they educate the users such as my parents into creating a Firefox account or assuming that Firefox equals privacy, which is clearly not the case.

I didn't make that claim. I just said I immediately close them and don't mind them much because I basically only restart the browser when I reboot the PC (so about once a month because after that all kinds of bugs start to appear).

Of course I see them as problem, I assumed that was obvious from the rest of my comment.
