Desktop screen share failing with TypeError: e.split is not a function

[Kyoshiro-san]

Hi,

I'm trying to get desktop screen sharing to work using Firefox 59 on Ubuntu/Linux 17.10 and OpenFire server 4.2.3, ofmeet 0.9.3. When I click on the screen share button, I get an red popup box saying Screen sharing extension failed to install and a few JS console errors:

[react/features/base/tracks/functions.js] <t.a/<>: Failed to create local tracks Array [ "desktop" ] TypeError: e.split is not a function
[conference.js] <_handleScreenSharingError>: failed to share local desktop TypeError: e.split is not a function
[JitsiMeetJS.js] : UnhandledError: null Script: null Line: null Column: null StackTrace: TypeError: e.split is not a function

I thought there was no need for an extension anymore using Firefox > 52, am I wrong ?
What could be the problem here ?

Thank you very much,
Kind Regards.
