I held off on Windows 10 for as long as I could until Adobe, and therefore my job, required it. Now this nonsense. I hope this isn't the start of them joining on the web DRM bandwagon.
If safari is supported, then there is no reason to not supporting Firefox. What key features supported by safari required by adobe that's not supported by Firefox?
Out of all the modern browsers, it’s always Safari that I end up needing to write compatibility code for. I’m sure the app works fine on Firefox, they just haven’t tested it.
Tbf, while daily-driving Firefox I do occasionally encounter websites (mostly web apps) that do not work on Firefox. But it's often a pretty simple fix, like sometimes I can get around it myself just through Dev Tools shenanigans.
