Microsoft and Flash

Meanwhile Microsoft works on moving Edge from EdgeHTML to Chromium. As Microsoft’s Edge will be a Chromium based browser, we can easily say it is a matter of time for Edge to follow Chrome’s 76 update steps. Flash is disabled by default. Edge will do the same, whether it will be launched sooner or later.

As for Internet Explorer (IE) and the old Edge, in 2017, Microsoft informed that somewhere in the middle or an end of 2019, these browsers will by default have a disabled Flash. Users will have to manually enable Flash in browser settings panels to view content. The change has not yet appeared in any browser.
Since Microsoft updates old-Edge only when it releases an update for Windows 10, the next opportunity for this will be an update in the autumn.

Microsoft hinted that it would keep old-edge even after the full delivery of Chromium Edge, so it would have to manage multiple browsers — IE, also for Windows 10 users and those who still running Windows 7.
