Zoom download and installation instructions for Mac computers using the Firefox browser.


If your host is using our Zoom platform, this must be installed on the device you will use to participate in a session. Zoom only needs to be installed once per device. 


You will be automatically prompted to download and install Zoom when attempting to join a meeting but we recommend going through the process below and testing the connection/audio/video ahead of time to be sure everything is working before an actual session. If you have any questions, or would like to schedule a test session, please don't hesitate to contact the support team at (888) 540-2829, or email us at [email protected] (please include your timezone and that you want to test Zoom).
