Webex-addon not working @ chrome|firefox/Ubu 20.04

I added the webex chrome extention and the firefox addon. On both i go to

 www.webex.com/test-meeting.html

and click at join. The follwoing msg comes:

 Your browser, browser version, or operating system is currently unsupported.

      For details, check the *system requirements*.

When i click on the link (system requirements) it sends me to the standard help center.

Most similar problems on the web are for older ubuntu, like < 18.xx. I am using Ubu 20.04, 64bit, Cisco Webex Chrome/firefox Extension Version 1.8.0, Updated last on June 2, 2020. Audio/camera work fine under MS Teams (for linux).

Can anybody help me?


I'm quoting from this thread: WebEx on Ubuntu 18.04


Given that I'm in an academic environment and our institution uses WebEx, I've kept at this problem and think I've solved it in an incredibly easy way.

My system - System76 galp3-pro (GalagoPro); Intel Core i7-8565U; Mesa Intel UHD Graphics 620 (WHL GT2); 32 GB RAM - Running Ubuntu 18.04.4 LTS AMD64 (not Pop_OS) - Running the latest Intel Video Drivers from GIT (https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers) - Using XServer-Xorg for the session, not Wayland - Using UNITY 7 as window manager (from the UNITY Maintainers PPA)

Steps to get WebEx working:

  1. Using Firefox 74.0; download USER-AGENT SWITCHER (https://mybrowseraddon.com/useragent-switcher.html) from the FF Add-Ons Using the UAS; choose "Windows 10" as the Operating System and "Chrome" as the browser.
  2. Navigate to WebEx Test Meeting and join a test meeting. The WebEx website should permit the automatic downloading of the Chrome Plug-In and you should now be able to use WebEx as a native Windows10/Chrome user would. Native microphone, sound, webcam worked.

This worked for me.
