I pretty much use #Firefox 100% these days. Safari and Firefox are all I have installed on the primary machine. As long as I am working from home, work machine is going to be primary machine. I'm not going to mess about with changing monitor cables and I don't have USB-C on my personal laptop.
Although, I got (for free!) a couple of new-to-me laptops I haven't even had a chance to boot up. ugh.
