It’s also trivially easy to disable ads in the Windows start menu, but the fact that they’re even there is shocking.
I use Firefox because I want to do at least something to keep the web browser market from becoming a monoculture again, but they’re making it increasingly hard to justify.
I think I understand where he's at. If your web site has compatibility issues with smaller browsers like Firefox at 3%, Opera at 2% etc. then you could be losing out on 5% of your sales. If you were to approach any CEO and ask if they'd be interested in an initiative to increase sales by 5%, they would most likely express an interest.
there is good chance whoever site didn't worked for will just switch to chrome for that site. I did that few times.
We have "any browser above 5% market share" in deals with our clients. So FF testing is not even required
Sadly Firefox has been out of our browser matrix for several years now, it is only taken into consideration by FE teams when the customers explicitly ask for it being supported.
I also use because I care, but at 3% hardly any business does any longer.
