Now WebEx and Skype for Business do not work with Firefox, what is the solution?

Now that Firefox does not support plug-ins. Many applications like WebEx and Skype for business do not work. What is the solution from Mozilla to this issue? I've search this forum and in some the recommendation is to install older versions which does not seem practical.

hi, i'm not familiar with firefox but joining a webex meeting via new firefox versions without npapi plugin support works fine here (cisco is providing a webextension to facilitate this process) - what problems do you have with it?

The tests at Webex and on24 for compatibility fail with Firefox 65.0.2 from openSuse 42.3. Usually can't join a webinar. The Flash Player PPAPI plugin 27.0.0 is installed and configured to activate always (and not block dangerous content). Both webinar platforms worked with earlier versions.
