In Mozilla® Firefox® update 51, functionality of the VidyoDesktop™ guest links on Windows® is impaired while in mixed security mode.
If VidyoDesktop is open and you click on a Vidyo guest link using Mozilla Firefox 51, the browser will show “connecting”, however it will never actually transition to VidyoDesktop (where you would be prompted to enter your name).
Mozilla® has released a temporary fix in the form of an add-on. To ensure your browser obtains this add-on update, please follow the instructions on our Support Portal.
If you become aware of any customers with this issue, please direct them to the Impromp2u support portal, where they will be able to find the solution.
