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.
