When I use Firefox on my work laptop I get harassed by Microsoft. They keep signing me out of Outlook and saying they wouldn’t have to do that if I was on Edge. And they occasionally put up a message on Microsoft To-Do that they won’t sync my changes because I’m on an unsupported browser. This doesn’t happen with Chrome so unfortunately that’s what I use now. It’s not Firefox’s fault, it actually works better for me everywhere else, but I wanted to stop signing in 6 times a day.
