I was going through a Greenfield survey and got this message

Firefox doesn't know how to open this address, because the protocol (ttp) isn't associated with any program.
After I clicked ok on the pop up the page was just blank. I don't know if I should report this since I use Firefox and I know the preferred browser is IE.

If this is something I should report, how do I do that?

Thanks for any help, normally I don't have any problems so I don't know what to do
