The FTC is taking an active interest in the way Adobeís Flash installs its tracking cookies, according to a report. Privacy advocates have been arguing that the Adobe Flash Player, installed in up to 98 percent of PCs around the world, does not allow standard privacy controls to delete its Flash cookies. Critics argue that when users use privacy controls to stop cookies being set, or delete existing cookies, that this function works for all other apps and plug-ins except for Flash.
