Its plug-in version is available for every major web browser. Google Chrome comes bundled with the sandboxed Adobe Flash Player plug-in.
Adobe Flash Player parses and runs SWF files. It supports vector and raster graphics, 3D graphics, an embedded scripting language called ActionScript, and streaming of video and audio. According to Adobe's statistics, Flash Player has been installed on more than 1.3 billion systems. It has already become the standard for delivering high-impact, rich Web content.
