Hangouts didn't work for a long time on Firefox. They fixed it around a month ago or so, but that's pretty much three years after they knew that this problem would arise (deprecation of NPAPI plugins in Firefox). For other parts, for example GMail, I've heard that they don't work as well on Firefox. And to some degree, this is also just what I expect to see more of in the future, as outside of G Suite they're not exactly known for treating other browsers well either. Android Firefox in particular gets bullied by Google a lot. Last time I checked, the Google Custom Search that webpages can embed, just straight up returned a 404 when contacted by a browser with Android Firefox user-agent. And they serve some age-old version of google.com to it.
