End of Life announced for FlashPlayer
Given this progress, and in collaboration with several of our technology partners – including Apple, Facebook, Google, Microsoft and Mozilla – Adobe is planning to end-of-life Flash. Specifically, we will stop updating and distributing the Flash Player at the end of 2020 and encourage content creators to migrate any existing Flash content to these new open formats
Flash & The Future of Interactive Content
Chrome will continue phasing out Flash over the next few years, first by asking for your permission to run Flash in more situations, and eventually disabling it by default. We will remove Flash completely from Chrome toward the end of 2020.
Saying goodbye to Flash in Chrome
We will phase out Flash from Microsoft Edge and Internet Explorer, culminating in the removal of Flash from Windows entirely by the end of 2020. This process began already for Microsoft Edge with Click-to-Run for Flash in the Windows 10 Creators Update. The process will continue in the following phases:
Through the end of 2017 and into 2018, Microsoft Edge will continue to ask users for permission to run Flash on most sites the first time the site is visited, and will remember the user’s preference on subsequent visits. Internet Explorer will continue to allow Flash with no special permissions required during this time.
In mid to late 2018, we will update Microsoft Edge to require permission for Flash to be run each session. Internet Explorer will continue to allow Flash for all sites in 2018.
In mid to late 2019, we will disable Flash by default in both Microsoft Edge and Internet Explorer. Users will be able to re-enable Flash in both browsers. When re-enabled, Microsoft Edge will continue to require approval for Flash on a site-by-site basis.
By the end of 2020, we will remove the ability to run Adobe Flash in Microsoft Edge and Internet Explorer across all supported versions of Microsoft Windows. Users will no longer have any ability to enable or run Flash.
