Besides the extension, you have to run the Cisco_WebEx_Add-On.exe they download for you. They should explicitly say that the extension doesn't work by itself. It needs the extension to function.

funktioniert unter Firefox nicht. Funktioniert nur unter Chrome ;-)

Absolutely crap! This is not a true extension. It forces you to download the crappy webex software and install it!

@Cisco-Webex
Just accept guys, that you should treat mozilla firefox addon with compatibility in mind ...
Merry Christmas and a flawless 2022, concerning the first web browser Globally (.)
;-)

En linux funciona (firefox) sin problemas, en windows no reproduce el audio de la reunion (chrome)

Somehow, i couldn't get webex and firefox to work together. I can't login to my organisations webex platform. but in edge, and others no problem.
webex seems can't to work with firefox. are you guys okay?
i followed the instructions given at webex.com, but to no avail.
it frustrates me and motivates me to write this review.
TLDR webex for firefox sucks!

does NOT work....none of vital information is accepted

funciona como debería, aunque me encantaría que dieran mas opciones de audio

Doesn't work on Firefox, Manjaro Linux. Better move to any other best alternatives like google meet or Microsoft as they support native desktop versions or they only depend on websites.
And another worse is that, viewing recorded meeting of web-ex through Android is not possible.
How it would be possible for everyone to buy a laptop or desktop?
It would be better atleast if web-ex has support to play its recording videos in Android which is almost nearly impossible.

I don't know what it does, but Webex works.

Slow. Consumes lots of CPU. It's faster to cut and paste the meeting URL into the app.
