With the entire computing industry moving away from Flash, Fedex is jonsin' to get users to continue to use it. Problem is, Apple, Chrome, Firefox and Microsoft EDGE doesn't support it anymore. You can still install and activate it, but by default, it either doesn't come with the browser or it's turned off by default. Fedex's problem is that their website really doesn't work without it. So Fedex is offering to pay you $5 to turn it on. Leo says that Flash is a huge source of security issues, malware, and phishing scams. So he advises not to take the bait and leave it off.
