Firefox 53 not compatible with Cisco Webex
Each time I try to launch a Webex meeting in Firefox, it looks as if it will open the Webex--even loads a portion of the meeting room, then results in a Firefox error message saying, "This version of Cisco WebEx does not support your version of Firefox. Try one of the following options: Use a different browser to join the meeting. Install Firefox version 51 or earlier."
I checked my version of Firefox and it says 53.0.2 so according to the error message, this should work? Unless "earlier" means a version before 51. Either way, I'm not sure how to solve this problem. Is it possible to go back to a previous version of Firefox if that's indeed what the error means?

hi, have you tried cisco's webex addon yet?: https://addons.mozilla.org/en-US/firefox/addon/cisco-webex-extension/
I tried it, and restart Firefox and still had the same issue. I went in to make sure the add-on installed and it did. Any other suggestions?
You can try the Firefox 52 ESR version to see if that version works.
You can install a portable (ESR) Firefox version to access websites that do not work with the current Firefox release. The portable version comes with its own profile folder and doesn't interfere with currently installed Firefox versions.

If you install multiple releases then make sure to create a separate profile for each version.
