"All browsers do this, including Chrome."
Yet Mozilla apparently wants us to believe Firefox is different. If in fact it was a browser designed for users cf. advertisers, it would surely choose a different design. Alas, it chooses essentially the same design geared toward facilitating online advertising.
On the one hand HN commenters defending Mozilla argue Firefox is different, in fact better than Chrome. And yet on the other hand Firefox more or less matches Chrome, "feature" by "feature". HN commenters claiming to have worked for Mozilla in the past have stated this is intentional and makes sense. They are likely correct.
Anyway, I am not a graphical browser user. I use different, text-only software. I see no ads. This works and makes sense for me.
Comparing graphical browsers does not make much sense for me. To me, they all suck. They are more similar than different.
For others who rely on these graphical browsers, comparisons might make more sense.
Computer owners and internet subscribers striving to control their hardware, e.g., trying to prevent unwanted UDP and TCP transmissions. These so-called browser "features" seem to benefit advertisers and advertising corporations more than they benefit computer owners and internet subscribers.
