By porting Flash Player to PPAPI, Google’s engineers were able to stuff the Adobe plug-in into a “sandbox” as robust as the one that protects Chrome itself.
“Windows Flash is now inside a sandbox that’s as strong as Chrome’s native sandbox, and dramatically more robust than anything else available,” stated Justin Schuh, a Chrome engineer.
Windows XP powered 46.6 percent of all Windows PCs that went online in July, a slightly larger share than the quickly-gaining Windows 7. The port of Flash to PPAPI will reduce Flash crashes by 20 percent, and prepares Chrome for its debut on Windows 8, the upgrade Microsoft plans to start selling Oct. 26.
“Because PPAPI doesn’t let the OS bleed through, it’s the only way to use all Flash features on any site in Windows 8 Metro mode,” Schuh wrote, referring to the tile-based environment that, along with a traditional desktop, comprises Windows 8.
