Make sure that you are using Firefox Nightly and you enabled: media.getusermedia.screensharing.enabled flag from about:config page. You also need to add your domain in "media.getusermedia.screensharing.allowed_domains" flag. If you are using WinXP then also enable "media.getusermedia.screensharing.allow_on_old_platforms" flag. NEVER forget to use "only" HTTPs for screen capturing! RTCMultiConnection.js:361:17
