I am having the same problem. It just started today. Every time I click home page, it goes to http://?fr=fp-tyc
Does anyone know how to fix this?? Resetting home page only works until you close the window. When you start a new window it goes back again to the error.
I have been having the exact same problem for the past few days. Very frustrating! Nothing seems to fix it. I've tried resetting the home page, but that's only a temporary fix. I've tried disabling various add-ons and extensions, including Yahoo toolbar, and restarted Firefox, but no luck. I've scanned for viruses and malware, but that didn't solve this problem either. My Firefox is up to date. I'm just hoping that Firefox will come up with a fix now that it is aware of the problem.
