Webclient screensharing / remotesupport not working on Firefox

[IBML]

I discovered an issue on 15.5SP4 on Webclient
The screen sharing / remote support feature is not working on the latest Firefox version.
Works on Google Chrome, but using Chrome is not an option.

The buttons are there, but nothing happens, clicking on them.



Known issue ?

Hello @IBML

Please note that Screen sharing and Remote control are not supported in Firefox as it is stated in the webmeeting user manual. You will need to use Google Chrome to use those features.

Using Googlew Chrome is not an option
Is this going to work in Firefox ?
Without Firefox / Edge / Safari Support this feature is useless industry wide
