When it first came out, Firefox was faster, lighter and offered way better function than the alternatives at the time. Since then, competition has been fierce in the browser market and they’ve done little to distinguish themselves in any major way from their competitive set.
Until they do something so vastly incomparable in the market, they gonna continue to falter.
It really comes down to two things.
- Do you want to encourage more privacy across the web?
- Do you want the web to be more decentralized?
If you want more privacy and less centralization, you should use FF. I don't think it is just about the services that they offer. I think we can go deeper and talk about the future of the web in general and how our choices affect that.
Edge vertical tabs is your best choice if you must use a chromium browser, however it is a weak imitation of TST.
How is that possible? Do you never compare things? Or do you only compare things for which there are fewer than 10 alternatives?
What makes it weak?
I'm not going to tell anybody else what their reasons are or should be, but for me voting against the browser monoculture was a reason to switch.
Most people won't care enough, of course, but to me it's not that different than voting for a candidate in an election who might not be the absolute best fit for my personal interests but who seems better for an overall political culture, or some other similar compromise.
