Adblock Plus extension breaks Kopano WebMeetings

When using the Adblock Plus extension in Chromium based browsers, Kopano WebMeetings cannot create a call and fails with 'Oops, PeerConnection failed - check your settings'. One possible reason is the Adblock Plus extension which replaces the WebRTC implementation inside iframes in a way which is incompatible.

The recommended course of action is to remove the Adblock Plus extension and replace it with uBlock Origin. Make sure to reload Kopano Webapp after you have removed Adblock Plus.

If you cannot or do not want to remove Adblock Plus, a workaround is to 'pop out' Kopano WebMeetings into a separate window.
