Why the hell does Cisco Webex require "Access your data for all websites" permissions?

Cannot get to work

Pero que broma es esta

Does not work, and as far as I can remember, it has never worked properly in Firefox. Always have to download a stand-alone app to run the meeting. Would be nice if the Devs would fix it, seems as though lots of people have this problem...

Le racourci ne s'affiche pas! et malgré plusieurs tentatives, incapable de se connecter!

Slow and clumsy in Windows (have to change the audio settings every time) and won't install at all on the current Android version... Surely Cisco could do better than this?

Webex doesn't work at all on Firefox / Chrome on Linux.

Installed Firefox Add-on from addons.mozilla.org. Navigated to a webinar hosted with webex, and was asked to isntall cisco_webex_add-on.exe. What? So uninstalled the add-on, and installed the exe. Shows as installed. Navigate to the webinar, and am prompted again for add-on installation. This was attempted with Firefox Quantum version 61.0.1. I had to use IE 11, because I couldn't get Firefox and Webex to play nice together. 1 star. Ideally, this add-on would work like most other add-ons, with easy install, and it just works. Would not recommend until you see a youtube video showing you this is working.
