Skype says it's working to bring the extension-free workflow to Chrome and Firefox, and will do so when those browsers work with the H.264 video codec. In addition to reducing the annoyance of having to install a software add-on to get Skype up and running in your browser, plug-in free support also opens up the ability for the full service to be used on devices like Chromebooks. This new version is available for preview starting today, but the company plans to roll it out to all Edge users by the end of the month.
