In what appears to be an awesomely short-sighted move, FedEx is effectively slipping users $5 to install Adobe Flash Player on their PCs. Adobe Flash Player has a pretty horrible security record, and many sites are moving away from it to other technologies, such as HTML 5.
Flash Player allows your web browser to display sound and animations on a web page, and in this case it is used for FedEx's Office printing service.
You might think a huge (and rather high tech) company like FedEx would alter their web content to use HTML 5 - or indeed anything but Flash Player, but instead they offer a $5 rebate for your cooperation if you go ahead and install it.
Weird, and not in a good way.
