How to control what window to share from Firefox or Chrome

Super Contributor

Hi there,

Our users informed that they are not able to control what windows Skype for Business (Office 365) is sharing when they are trying to share Firefox or Chrome. Steps to reproduce:

1. Open Firefox twice (two processes, not two tabs) or Chrome

2. In the online meeting start sharing the Firefox

You should see under the dialog there is actually two lines and when you enable the share both of the windows gets shared. Compared to the any other applications (notepad, rdp, cmd, IE, etc..) users can select what to share.


This is of course a security issue if your user has used to share window by window. But in the meeting user has browsing internal pages without knowing that others can see that as well.

If you open several windows of chrome and look in the task manager, you will still see only one instance of chrome. With two notepad windows open, you will see two instances of notepad. So my guess is that chrome and firefox is designed to run only one instance even if several windows are open.



Actually I do have two firefox processes, some how:


PS C:\> Get-Process -Name fir*

Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName
-------  ------    -----      -----     ------     --  -- -----------
    525      88   327560     356816     324,79   3296   1 firefox
    834      95   251248     288136     645,52  10288   1 firefox


But still there is only one share available.

They are still collected under the same umbrella in Task Manager:



That is very true :)


Users of course don't see the differences, but let see if Microsoft could fix this.
