Thanks for your email and welcome to the community.
There is a Uservoice open here for exactly this
And here specifically for Firefox
I voted! Would recommend you vote and draw as many people to this as possible to get it in front of Microsoft. I will also raise it at the Teams AMA next Wednesday and relay it back to Team so it has their attention.
I hope that I answered your question. If I have please like the post and mark it as the solution. I look forward to more of your questions in the future. Thanks again for reaching out.
