Flash Google Chrome sentenced to death at the end of the full implementation of HTML5-Flash,HTML5,Chrome-IT information

May 16 morning news, Google has announced a plan to replace Flash with HTML5, the Chrome browser's default option.

Starting from 2016, fourth quarter, Google plans to remain dependent on the top 10 domain names provide the default Flash plugin Flash support. As long as the site offers HTML5 experience, then Chrome will show such experience. If the site must use the Flash plug-in, then the user will be asked whether to allow a Flash plugin to run.

The last few years, Flash is fading away. On one hand, Flash poses a serious security problem, Flash plug-ins are often exposed to new security vulnerabilities. The other hand, the market will gradually abandon Flash into HTML5. In addition, the relationship between the Chrome browser and the Flash is particularly complex.

Although Google chrome integrates Flash plug-in by default, but Google is gradually played down the importance of this plugin. September 2015 start Chrome 45 auto pause very important Flash content, including advertising, animation, as well as all other "does not belong to center the page" content. At present, the move will spread to the center of the Web page content, that is, games and video.

Google's plan is that Flash Player will remain bound to the Chrome, but Chrome will no longer pass Navigator.Plugins () and Navigator.MimeTypes () defaults to push Flash Player.

-If the site provides HTML5 experience, HTML5 will be the default experience.

-When users find Web site requires Flash Player, push notifications will appear at the top the page that asks the user whether to enable Flash Player allowed on the site.

-If the user accepts, then Chrome will inform the users of Flash Player and refresh the page.

-Chrome will save this settings for a user, for the user to then access.

-In order to avoid users to receive push notifications, we will be top 10 Flash-dependent site (according to usage) on the white list. The white list will expire after one year.

Google says this whitelist is designed to "reduce the initial impact on users, avoid excessive pop-up notifications." If Google is implementing a whitelist of sites including YouTube, Facebook, Yahoo, VK.com, and Live.com, and Yandex.ru and the OK.ru, Twitch.tv, Amazon and Mail.ru. Google promises in a year's time, according to the website of use of Flash is updated on a regular basis as a white list.

If the user allows Flash Player to run, then Chrome will save this preference, and refresh the page with Flash enabled. If the Web site requires the user to download Flash, then Chrome will intercept that request and popup "allows Flash Player......" the message bar.

Google also plans to add policy control for enterprise users. Users can set to "allow websites to run Flash", "allowed sites......", and "never run Flash content." User management can also be based on a single site preferences.

谷歌Chrome判Flash死刑，年底全面推行HTML5 - Flash,HTML5,Chrome - IT资讯

5月16日上午消息，谷歌已公布一项计划，用HTML5取代Flash，作为Chrome浏览器的默认选项。

从2016年第四季度开始，谷歌计划只为仍依赖Flash插件的前10大域名提供默认的Flash支持。只要网站提供HTML5体验，那么Chrome就会展示这样的体验。而如果网站必须使用Flash插件，那么用户将被询问，是否允许Flash插件的运行。

过去几年，Flash正逐渐淡出。一方面，Flash带来了严重的信息安全问题，Flash插件常常被曝出新的安全漏洞。另一方面，市场也在逐渐抛弃Flash，转向HTML5。此外，Chrome浏览器和Flash之间的关系尤为复杂。

尽管谷歌浏览器默认集成了Flash插件，但谷歌正逐步淡化这一插件的重要性。2015年9月，Chrome 45开始自动暂停不太重要的Flash内容，包括广告、动画，以及其他一切“不属于网页中心”的内容。目前，谷歌此举将推广至网页的中心内容，即游戏和视频。

谷歌的具体计划是，Flash播放器仍将捆绑至Chrome，但Chrome将不再通过Navigator.Plugins()和Navigator.MimeTypes()默认去推Flash播放器。

-如果网站提供HTML5体验，那么HTML5将成为默认的体验。

-当用户发现网站需要Flash播放器时，网页最上方将出现推送通知，询问用户是否允许在网站上启用Flash播放器。

-如果用户接受，那么Chrome将会告知用户Flash播放器的存在，并刷新页面。

- Chrome将保存用户的这一设置，供用户随后访问。

-为了避免用户过多地收到推送通知，我们将把依赖Flash的前10大网站(根据总使用量)列入白名单。这一白名单将在一年后过期。

谷歌表示，设计这一白名单是为了“减少最初对用户的影响，避免弹出过多通知”。如果谷歌现在就执行这一白名单，那么其中的网站将包括YouTube、Facebook、雅虎、VK.com、Live.com、Yandex.ru、OK.ru、Twitch.tv、亚马逊和Mail.ru。谷歌承诺，将在一年时间里，根据网站对Flash的使用量定期更新这一白名单。

如果用户允许Flash播放器的运行，那么Chrome将保存这一偏好，并在启用Flash的情况下刷新页面。如果网站要求用户下载Flash，那么Chrome将拦截这一请求，并弹出“允许Flash播放器……”的消息栏。

谷歌还计划为企业用户添加策略控制。用户可以设置为“允许网站要求运行Flash”，“允许网站……”，以及“从不运行Flash内容”。用户也可以根据单个网站管理偏好。
