Am I the only one who thinks it's awful that a website developer is even trying to detect and disable this feature? As a user, the interface to my OS and browser remaining consistent is much more important than disabling a single feature that may cause trouble on a single website. In fact, I find it presumptuous that they are trying to even detect this, and then tell the user to disable it system-wide!
