The stupid prize is that by the time you decide it's time to use a different browser, Firefox and Safari have been rendered totally unusable by developers only targeting Chrome because that's all they have to do.
I use it every day as my primary browser, but there's definitely been an increase in applications that will not work except on Chrome. It's not text content that's ever the issue, it's SaaS products.
It's your anecdote vs. mine, but this is not my experience. I find that Chrome is better for Google Meet (not surprising.) Other than that FF is fine. In the last 4-5 years have become increasingly similar and easy to support as a developer.
Out of the ones that you use, maybe (I've actually never had a problem with Google Maps). There are several applications that I have to use for work that either don't work on Firefox or have limited functionality, Slack being one of them (huddles only work in Chromium or in the Electron app).
