Collaborate 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.

Collaborate only supports the most recent two stable channel releases of browsers.
|Google Chrome™||Windows®, macOS, Ubuntu||Android™|
Note: Firefox ESR is not supported
|Windows, macOS||Not supported|
|Safari®||macOS 10.13+||iOS® 14+, iPadOS|
|Microsoft Edge® (Chromium)||Windows, macOS||Android, iOS|
Certified browsers and operating systems
Class Collaborate is regularly certified against the following combinations of browsers and operating systems. These combinations also reflect the areas of strongest support.
|Google Chrome||Windows 10 & 11, macOS 10.14+||Android 9+|
|Firefox||Windows 10 & 11, macOS 10.14+||Not supported|
|Safari||macOS 10.14+||iOS 14+|
|Microsoft Edge (Chromium)||Windows, macOS||Android, iOS|
For macOS, iOS, and iPadOS, only the latest two major releases of each operating system are certified, using the most recent stable release of Safari on each system.
For Windows, only Windows 10 is certified.
Only the most recent two stable channel releases of Chrome or Firefox are certified. When new versions of operating systems or browsers are available, the older ones drop to provisional support.
In some cases, and in particular for iOS and ChromeOS devices, the providers set a date after which they won’t allow their devices upgrade to recent versions of applications and browsers like Safari and Chrome. Unfortunately, this isn’t something we can influence. If you stay on an unsupported old browser, your experience with Collaborate will be impacted. It may impact your ability to join a session. Keep the impact in mind when considering the lifecycle of your device.
Tip: Google publishes in advance the update expiration date of ChromeOS devices.
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.
|Google Chrome||Windows 8, macOS 10.13+, Ubuntu||Android 8, Chromebook|
|Firefox||Windows 8, macOS 10.13+|
|Safari||macOS 10.13+||iOS 13, iPadOS|
Other Linux distributions may be operational with Chrome and/or Firefox but are not tested and not supported.
Virtual Machines may be operational with any of the above operating system and browser combinations, but are not tested and not supported.
Unsupported browsers may work properly with Class Collaborate. If you experience issues, update your browser and operating system to the latest version. If after the update you’re still experiencing the same issue you may have your administrator submit a support case on Class Community and Support.
Attention! When providers have decided to end support for their own browsers and operating systems, we have to as well.
- Support for Internet Explorer was dropped on March 21, 2019 due to dropping support for Flash plugins.
- Support for Windows 7 will end on January 1, 2021 due to all support from Microsoft ending in January 2020.
- Firefox ESR is not supported.
Application Sharing is available on Chrome, Firefox, Microsoft Edge (Chromium), and Safari with no plugins required.
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.
