...you would think that a company like Cisco has decent QA and/or reads at least the reviews here.

Webex meeting audio connection stuck at "connecting". Switch to IE or Jabber works.

Yeah, as someone commented here this really doesn't work on Linux 64bit. Why? Is that so hard? Not to mention 64bit is probably 99% of all Linux desktop installations these days.

Merci bcp

Every time I want to join a Webex, I have to reinstall the extension and restart Firefox.

The addon is just a thin (technically unnecessary) launcher to start a Java app. Which in turn uses binary JNI extensions which are only provided as 32-bit binaries, so it fails on 64-bit systems, which is most systems these days.

Can you please switch to industry standards? It's not the 20th century anymore.

Webex meeting page will keep asking to install addon. If you restart Firefox (54.0.1 (64-bit)) the addon will work and open up the Webex meeting. You have to repeat the process of installing the addon and restarting Firefox for each meeting.

The WebEx page says an actual Firefox will work. Starting the add-on it claims to need 51 or earlier.
No wonder about the web site statement. It's almost 3 years old.

Love it!

Most of the times it does not even work... very unprofessional that there is no development for more days

It's not worked!!!!!!!!!

Seriously, how lazy was this? Brand new version of the plugin due to a security error, and it doesn't support Firefox 52!

Complicated

Just doesn't work. It keeps asking to download DMG file on macOS Sierra 10.12.5 and FF 54.0.1

I can't believe this can't be fixed.

I've got the latest version of firefox for Mac (at IBM) and it says version 52, so the version must be for a different OS. I had to use Safari, and it worked fine using that browser, no add-on necessary.
