I don't understand what you need. Go and try Firefox. As a person that uses Firefox as a daily driver, both at work and at home usage, I can't recall when I had to switch to Chrome. In 2010, maybe. I don't know what other "awe-inspiring endorsement" you need.
Firefox did not save my marriage nor did it make me a million dollars, no.
Do you use Firefox because it’s a better browser or because of philosophical reasons? If it’s the former, then I want to know that somebody thinks it’s the best way to browse the web. If it’s the latter, then tell me it’s worse but the politics of supporting Google are distasteful to you.
Don’t tell me it’s “very usable” because I’m going to interpret it as the latter which may or may not be correct.
I actually don't use ad blocking. If there are ads and I don't want to see them, then I don't visit that site again. The site has chosen their business model and I can choose which sites I want to visit.
I also like buying things that I might like, so seeing ads (and ads that are targeted to me) isn't necessarily a bad thing to me.
