| 1 | Mozilla Firefox added support for screensharing in Firefox 33. The feature is currently only enabled for a small number of whitelisted domains which can be specified in the preferences.
|
| 2 | This extension is a [bootstrapped extension](https://developer.mozilla.org/en/Add-ons/Bootstrapped_extensions) that adds and removes [simplewebrtc.com](https://simplewebrtc.com) from the screensharing whitelist preference without user interaction.

|
| 4 | Firefox 52 [will drop](https://www.mozilla.org/en-US/firefox/52.0a2/auroranotes/) the use of a whitelist and therefore also the need for a domain-specific extension.
