Chrome, Microsoft Edge, and Safari have actually all been blocking Flash over the previous year, but Adobe is now preparing to eliminate support for it completely by the end of 2020. "We will stop updating and distributing the Flash Player at the end of 2020 and motivate content developers to move any existing Flash content to these new open formats," explains an Adobe representative.
A number of video gaming, education, and video websites still use Flash, and Adobe states it stays committed to supporting the technology until 2020 together with partners like Apple, Facebook, Google, Microsoft, and Mozilla. Microsoft states it plans to disable Flash by default in Edge and Internet Explorer in mid to late 2019, with a complete elimination from all supported versions of Windows by 2020. Google will continue phasing out Flash over the next couple of years, while Mozilla states Firefox users will have the ability to select which websites are able to run Flash next month and enable Firefox Extended Support Release (ESR) users to keep using Flash until the end of 2020. Apple is also supportive of the 2020 end of life for Flash, and Safari currently requires explicit approval on each website even when Mac users opt to install Flash.
2020 will mark an end of an era for Flash, but one that seems like it has been a long time coming. HTML5 standards have actually been implemented across all modern web internet browsers, and the need for Flash simply isn't there anymore. An end to Flash will bring with it obvious improvements in security and simply pure battery life on laptops and other mobile phones that still support the web technology.
