Collaborate Ultra requires a modern web browser with WebRTC support.

Collaborate requires certain permissions to function as desired. For example, Collaborate needs permission to access your camera and microphone so you can use audio and video. Give Collaborate permission when asked, and/or set up permissions in browser preferences.

Collaborate doesn't require or use plugins. All you need is one of the supported browsers.

Provisionally supported browsers and operating systems

The following combinations of browsers and operating systems are tested infrequently. They are supported, but in some cases, minor features might not be available, and using a certified combination is highly recommended.

Virtual Machines may be operational with any of the above operating system and browser combinations, but are not tested and not supported.

Application sharing

Application Sharing is available on Chrome, Firefox, and Microsoft Edge (Chromium), with no plugins required. It is not yet available in Safari stable releases. It may be made available in a future Safari stable release.

Application sharing is not available on mobile devices and tablets. If you want to share your screen or application you must be on a desktop computer.


If you are sharing video, you always see a preview of your video. This is on every browser and every device.

If other attendees are sharing their video, the number you can see depends on your browser and device.

  • FireFox: 2 videos
  • Sessions greater than 250: 2 videos
