I use google meet a lot. I need to screen my screen very often. i have used other web browsers which let to share a singe tab in the meet, but in firefox, can only get the option for either a window or an entire screen which is very inconvenient. I hope to hear from you soon because i use firefox and its be a shame for me to switch to other web browsers completely for this issue. My email is vijay.rh@gmail.com
