If you haven't tried in recent years, I'd suggest doing it again. Just as chrome has significantly increased in size and resource usage from its days of advertising how quick and light it is (it didn't stop advertising those points for no reason), Firefox has improved dramatically. I forget what post I was on but someone said there's always someone who badmouths Firefox simply because they haven't tried it recently. It really is true. Tech evolves so quickly these days, there's no reason to not give it a shot again.
