Could you walk me through the sequence of steps:

First, are you starting with a link that opens in Firefox, or are you already using your calendar in the Teams app?

When you open a link to a Teams call in Firefox, there should be three buttons with options to take the call in the browser or in the Teams app. Do you get that page? What messages do you get on that page?

Here's another thread about that page which might be the same issue, or maybe it's a different issue:
