Moving to Needsdiagnosis for further investigation.

so when accessing the page it starts automatically the download of the app.

const FirefoxFailed = ({ extension }: IProps) => {
  const isMac = isMacOs();

The detection is made here https://launch.lifesizecloud.com/static/js/components/Failed.tsx

const getComponentByBrowser = () => {
    if (isFireFox()) {
      return <FirefoxFailed extension={extension} />
    } else {

    }

Safari and IE11 are in the same boat than Firefox.

Not sure there is anything we can do at this stage, apart pushing to needscontact to ask them why this decision was made. They may have identified a technical roadblock. @lifesize is on github. Maybe @JustinTArthur knows someone at lifesize who could tell Mozilla and Apple what were the missing pieces?

On Safari it tries to download the app (if we authorize it) and at the same time scan the ports for the app. When we force the page to stop loading, it displays this screen.

That said it doesn't seem to work in Chrome either.
