WebEx on Ubuntu 15.04

Question

I can't get webex to work. When I click start "Enter Room" it gives me the helpful error of:

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

I've tried the instructions at:
How can I use Cisco WebEx in Firefox on 64-bit Ubuntu 14.04?
and
How can I use Cisco WebEx in Firefox on 64-bit Ubuntu 14.10
but there isn't a .webex folder to check for dependencies, clearly they had gotten further than my attempts before asking for help.

Maybe when Cisco say that Webex supports the latest firefox on a 4~5 year old Ubuntu they don't intend for Firefox 39 to work on 15.04.

Answer 1

The issue is not specific to that version of Ununtu, I'm seeing it on Ubuntu 18.04.

A workaround is to set up Firefox to remove all cookies from webex.com and .webex.com on exit. The downside is that you need to click through some dialogs every time.

Also, please note that only the "personal room" meetings are affected. Those meetings are insecure because people outside the company can guess the URL. Also, those meetings don't work is the organizer is missing. If you can teach your colleagues to create real meetings, you won't need to clean cookies and click on the bearded man dialog every time you join a meeting.
