And yet it looks outdated in its UI and UX, not to mention slow in MacOS I was a huge supporter of both Firefox and thunderbird in the early 00s but their UI/UX became so bad and so old (not to mention insecure) that forced me to go safari and Apple Mail. Both not great, but def much better than the Mozilla offerings. I wish they just rewrite the app from zero, with a modern architecture and UI, and supporting modern hardware.
