Firefox user but relatively ignorant on how tracking works.
FF does some good things to work around fingerprinting, although simply using FF puts us in a pretty small (marketable) group in the first place.

In particular, User-Agent strings are now a net-negative. I've never run into a website that doesn't work on Firefox. I do occasionally run into websites that claim to not work on Firefox. We software developers have shown that we can't be trusted with information pertaining to what browser someone is using, and as such should have the privilege taken away. If you're reading this, and you have access to a codebase that reads User-Agent strings for anything more than idle curiosity, just delete it and push to master.
I have a canvas element where the user needs to be able to both scroll and zoom with the mouse wheel. Generally, zooming involves scrolling while also holding the ctrl button down - except on MacOS, where it's cmd. I obviously want to use the operating system conventions that my users will be expecting, but the best way of determining that, that I've found, is searching for the string 'Mac' in the user agent string.
Like I say, if you know of a better way to detect whether I should be binding on ctrl or cmd, let me know! This is the first time I've used the user agent in a long time, and it feels like there should be a better system...
