VentureBeat:

The new Skype for Web client that Microsoft released on Thursday isn’t functional on several browsers, the company confirmed to VentureBeat today. The revamped version of the company’s messaging and video chat client only supports Microsoft Edge and Google Chrome — and Chromium-based browsers such as Vivaldi — but not Apple’s Safari, Mozilla’s Firefox, or Opera.

No real surprise but still a PITA for users who favor those browsers.
