Correct, specifically Firefox 78-esr. Life is hard, and my old mac is out of date. I still haven't found my preferred brand of linux, though sometimes the experience is better there(though not always). I usually also test in PaleMoon, Basilisk, and SeaMonkey, with varying degrees of success. I was lazy this time, and did not test further.

note, the current front-runner for my linux migration is MX. I'm still looking around though. will i ever actually make the plunge. one day my mac will just die i am sure.
