News and developments from the open source browser project
So long, and thanks for all the Flash
2017年7月25日火曜日
This morning,
Adobe announced their plans
to end support for Flash in late 2020. For Flash developers this will mean
transitioning
to HTML, as Chrome will
increasingly require explicit permission from users
to run Flash content until support is removed completely at the end of 2020.
HTML is faster, safer, and more
power efficient
than Flash and works across desktop and mobile. Three years ago, over 80% of Chrome daily desktop users visited sites with Flash. Today only 17% of users visit sites with Flash and we’re continuing to see a
downward trend
as sites move to HTML.
Over a three-year period, Flash usage has declined 80%.
We strongly encourage sites that still rely on Flash to make the move to HTML as there will be an increasing number of
restrictions
on Flash leading up to the end of support:
For sites that use Flash for gaming, a list of relevant APIs and demos can be found at
OpenWebGames.com
. We recommend exploring technologies like
WebAssembly
, which allows for high-performance computing.
For sites that use Flash for media, Mozilla’s
media migration guide
gives an overview of the APIs used to prepare, distribute and play media on the web.
Finally, for sites that use Flash for advertising, we recommend switching to HTML ads. Please work with your ad provider directly for this.
Flash helped make the web a rich, dynamic experience, and shaped the modern set of web standards. We recognize that any transition can have challenges, but we will continue to work closely with Adobe and the web community to ensure that users have a great experience and to help developers make the web transition to HTML.
