Cooperation with MS Teams app
With FF as default browser and the MS Teams app installed on W10, it appears to be impossible to activate the MS Teams app in FF. After clicking on the link to the meeting it is only possible to join the meeting via the MS Teams web interface. When Edge is the default browser, clicking on the link in the invitation gives a screen with three choices: Download MS Teams App / Join meeting via web interface / Open your Teams app. In FF the last choice is missing.
