Ask HN: Fired for Using Firefox

I'm here asking for advice, as I'm not sure what to do next.

I got a job 3 weeks ago, as a front-end developer. Obviously still on probation. Just got terminated today, reason given was I do not know how to use tools. They say the fact that I use Firefox as my preferred browser means that I'll most likely be terrible at cross-browser testing. That the fact that I do not use chrome dev tools is a red flag. Or the fact that I said I prefer using text editors (vs code) over full blown IDES (visual studio).

So my question is, is it fair to terminate a new developer because they use Firefox?
