If my company would tell me what browser should I use for work, I would look away from it. Fortunately all the companies I worked for didn't care what browser I use (even most people used Firefox anyway).
That's exactly what they want, because there's tons of other people dying to take your place that barely know what a browser even is, who won't complain, and who will work for less money.
At my (old) work we used Google Meet for meetings
I could not get audio on Firefox
It was the only site I ever found where I could not get audio and I suspect some Google malfeasance
When I initiated a meeting I used Jitsi, no such troubles
Obviously experiences will vary, but I have now had three organizations express concern (though not to the point of telling me I must stop) that I use third-party Firefox derivatives. This started with Pale Moon and then continued with LibreWolf.
The concern is that they "aren't authorized apps". As I've read it, this is a proxy for "we aren't certain these apps can be trusted, but nobody ever got fired for pointing the finger at Mozilla or Google when something goes wrong, but would be fired if they pointed it at this one random guy in the Netherlands".
