I had issues with Firefox sometimes not showing Google Docs / Sheets (which I use extensively) in other words, would not show any text / values, whereas Edge worked fine. So I switched and didn't go back.
Why would Google bother to make their apps work with a competitor? I used have to install an extension in Firefox to not have Office365 applications throw a fit about the user agent.
In a non-clown world they would do it because otherwise the anti-trust agencies would break them up. Of course in the corporate utopia we live in they don't get to experience these (dis)incentives.
