multi purpose screensharing от Sense

This extension allows for screensharing during videoconsults. On some systems and browser configurations sharing of your screen during a videoconsult is blocked, even on https certified sites. This plugin enables screen sharing regardless.

Use it during your talks, showing what you are doing, discuss a document together. Look at art together or give little live tutorials directly over the internet.

The plugin should work with any correctly setup WebRTC connection and works on any Navigator.getUserMedia() media to the screensharing capabilities of the browser. The plugin is implicit and meant for creators who are looking for an easy way to get their clients' screen sharing setup working on more, if not all browsers.
It should work on all websites, and you can easily direct your users to install this add-on. There is also a counterpart extension available for Google Chrome.
