If Firefox works for you, I'd recommend it. I could make a huge list of my subjective pros and cons, but who cares what I think?
The most important thing is that I'd recommend getting off Chrome, because Google is attempting to use their market position to make the internet worse for users. Try all the alternatives and see which one you like.
People are downvoting you, but you're correct. I don't work a particularly sensitive or interesting tech job, but we've had 2 candidates in the last year who were faking who/where they were. One had other people in the room feeding them answers. I'd expect weirdness in remote interviews as companies figure out how to navigate this.
