2017年7月25日，Adobe宣佈了其計劃在2020年底停止支持Flash的計劃。
20年來，Flash一直幫助您塑造遊戲，觀看視頻和在網絡上運行應用程序的方式。但是在最近幾年中，Flash變得不那麼普遍了。三年前，每天有80％的桌面Chrome用戶訪問帶有Flash的網站。如今，使用量僅爲17％，並且繼續下降。
這種趨勢表明，網站正在遷移到開放式Web技術，該技術比Flash更快，更節能。它們也更安全，因此您在購物，銀行業務或閱讀敏感文檔時可以更安全。它們還可以在移動設備和臺式機上使用，因此您可以在任何地方訪問自己喜歡的網站。
去年下半年，當網站開始需要您的許可才能運行Flash時，這些開放的網絡技術已成爲Chrome 的默認體驗。Chrome會在接下來的幾年中繼續淘汰Flash，首先會徵求您在更多情況下運行Flash的許可，然後默認將其禁用。到2020年底，我們將徹底從Chrome移除Flash。
如果您今天定期訪問使用Flash的網站，您可能想知道這會對您有何影響。如果該網站遷移到開放的Web標準，則除了應該再也看不到在該網站上運行Flash的提示之外，您應該不會注意到太大的差異。如果該站點繼續使用Flash，並且您授予該站點運行Flash的權限，則該站點將在2020年底前正常工作。
與Adobe，其他瀏覽器和主要發行商進行了許多緊密合作，以確保網絡準備好不使用Flash。我們支持Adobe今天的公告，我們期待與大家合作，使網絡變得更加完善。

Saying goodbye to Flash in Chrome
Today, Adobe announced its plans to stop supporting Flash at the end of 2020.
For 20 years, Flash has helped shape the way that you play games, watch videos and run applications on the web. But over the last few years, Flash has become less common. Three years ago, 80 percent of desktop Chrome users visited a site with Flash each day. Today usage is only 17 percent and continues to decline.
This trend reveals that sites are migrating to open web technologies, which are faster and more power-efficient than Flash. They’re also more secure, so you can be safer while shopping, banking, or reading sensitive documents. They also work on both mobile and desktop, so you can visit your favorite site anywhere.
These open web technologies became the default experience for Chrome late last year when sites started needing to ask your permission to run Flash. 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.
If you regularly visit a site that uses Flash today, you may be wondering how this affects you. If the site migrates to open web standards, you shouldn’t notice much difference except that you'll no longer see prompts to run Flash on that site. If the site continues to use Flash, and you give the site permission to run Flash, it will work through the end of 2020.
It’s taken a lot of close work with Adobe, other browsers, and major publishers to make sure the web is ready to be Flash-free. We’re supportive of Adobe’s announcement today, and we look forward to working with everyone to make the web even better.
