Google claims that this sort of flash rubbish accounts for more than 90 percent of the Flash on the web. In December, Chrome will make HTML5 the default experience for central content, such as games and videos, except on sites that only support Flash.
It is one of the nails in the coffin of Flash as the web slowly moves away from plugins in favor of HTML5. Since last year Chrome 45 began automatically pausing less-important Flash content (ads, animations, and anything that isn’t “central to the webpage”).
As Mozilla and Microsoft are expected to follow. However it looks like Google is already planning to move ahead. In an email the search engine outfit said:
“The end goal for all these browser makers is to push as many sites as possible to HTML5, which is better for both performance (lowering memory and CPU usage while boosting battery life) and in terms of web standards (which makes life easier for developers). Given Flash’s various vulnerabilities, there are obvious security gains as well.”
Google plans to have Chrome serve HTML5 by default in Q4 2016. Now the timeframe has been narrowed to December.
