Introduced in 2009 as a developer preview and launched officially in September, 2010, Chrome Frame is a free plugin for Internet Explorer 6, 7, 8 and 9 on Windows 7, Vista or XP SP2+. It provides a way for users of these older versions of IE to view Web pages coded with modern HTML5 elements like the canvas tag, as long as the website includes the appropriate meta tag.
Chrome Frame has helped Google's ongoing effort to win the hearts and minds of enterprise Internet users who, for one reason or another, haven't been able to switch to Chrome or Firefox. It has also made Microsoft look bad, as if the company can't adapt to modern Web technology.

Now that Microsoft Internet Explorer 10 is much more capable and Google Chrome dominates global browser usage, Google no longer sees a need to maintain the technology.
Google Chrome engineer Robert Shield argued that Chrome Frame's work is largely done. "Today, most people are using modern browsers that support the majority of the latest Web technologies," he said in a blog post. "Better yet, the usage of legacy browsers is declining significantly and newer browsers stay up to date automatically, which means the leading edge has become mainstream."
Nonetheless, the old ways die hard among enterprise organizations. In Google+ comment, IT consultant Austin Fatheree castigated Google for its plan to drop Chrome Frame. "You just undid YEARS of my work," he wrote, noting that some people and some companies, particularly government organizations will not or cannot upgrade. "Chrome Frame was the only way to roll out new [technology]."
Another Web developer, E.M. Marston, observed in a Google+ comment that in Canada, on her websites, one in four visitors still uses Internet Explorer 8 or earlier and that these people generally indicate that they'd upgrade if they could, but cannot because they're with a hospital, university or company that doesn't provide that option.
As an alternative to Chrome Frame, Shield suggests that IT managers employ Chrome for Business in conjunction with Legacy Browser Support, a Chrome extension designed to launch an installed legacy version of IE when necessary. Google wants Chrome to be a fully realized Web client rather than a parasite awakened periodically when an ancient version of Internet Explorer comes across HTML5 code.
