The problems I experienced that can be fixed in Firefox itself probably already got fixed.
My (personal) problem with Firefox is that functionally it's not Chrome and doesn't look/feel like it. The claimed non-functional improvements (privacy, freedom, ...) DON'T make up for the difference for me personally.
If Firefox looked and felt more or less exactly like Chrome for the functional parts then I would not have any problem switching for good. It's not at the moment, so this is what stops me from adoption.
I don't propose to change anything (you did). I was merely stating why I'm not on Firefox yet as a data point.
I see your point and it is absolutely within your right to stay on Chrome if you don't want to change. I've found it pretty much identical in terms of functionality and UX for the past decade though. Do you have any particular functional improvements in mind that you're missing in Firefox?
I think that personally I'm a lost cause. Either give me Firefox in a Chrome's pelt or I stay with Chrome. And maybe that's good this way: Firefox should just focus on new users and make the best browser for "them".
