I want to create a icon on a users desktop that launchs yahoo mail in it's own instance. (User profile I guess) Here's the background: I volunteer with a local seniors citizens organization to provide free computer support to seniors on a limited budget. Many seniors use yahoo becuase it was what they learned to use way back when and don't want to change. It is widely known that yahoo accounts have been subject to a recent spree of hacking using exploits, some of which do not even require a user to click on a link. I have seen firsthand 5 incidents where separate individuals using separate computers have had yahoo accounts hacked. One of my clients was an ATT customer, thus entitled to phone support. In a recent conversation with ATT support who uses yahoo for their e-mail services, they told me they are aware of the problem and the best solution is to logout of your yahoo account every time you are done using it. This is problematic for Senior Citizens who can't or won't remember passwords, they want it to just work. I began thinking that there must be a way to protect a user from at least some of these exploits. My finial idea is to create a desktop icon that will launch an instance of Firefox that is separate from the other websites that a user may be browsing. I think this could be accomplished using user profiles and some command line options. Any other ideas? Extensions? I'm thinking of blocking flash and java on that instance too.
