I would stop using Firefox if Enzor-DeMeo would block or cripple ad blockers. While it is not my main browser (Vivaldi is), I have 5 installs of Firefox Portable for different things, like one for YouTube, one for testing pages against Firefox and so on.
That's because their users are driven by opinions and principles, and those are the worst, most disloyal kind of users. They're always threatening to leave, and will take the slightest offense to do so.
Chrome wins because its user base doesn't care. The browser is just a tool, not a religion. It's installed, they use it, they're barely aware it exists and most of Joe Public doesn't even know Google makes it.
So sure. For you it's ad blockers. For someone else it's their donation plan. Or Google funding. Or their corporate structure. Or their management.
When your marketing is about something else, other than the product itself, you always end up with edge-case-customers.
People use Chrome because it's the best browser. Less than 3% use Firefox. And all I read from Firefox users is how bad everything is (or will be).
No, Firefox's market share isn't a foil to monopoly (Safari has 5 times more users. Crumbs Edge has twice the users.)
I care about Firefox, but I really just wish all the whiners would just do what they threaten and use something else. But they won't because everything else is worse (for some or other principles reason.)
Now I fully expect to be downvoted because the only people reading this article in the first place are Firefox whiners. Which is kinda my point.
It's pretty hard to recommend Firefox to others when everything written by existing users is so negative.
