hello naradoe28, this sounds like a problem possibly caused by adware already on your system. please go to the firefox menu ≡ > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc).

I'm getting so tired of having that darn 'block pop-up windows' checked..and it doesn't do a darn thing. Why am I getting garbage sites when I'm going to my normal browsing sites? (e.g. yahoo mail, etc) I now get this weird MacVx garbage showing up everywhere and a bunch of these error messages which are annoying (I also have a Mac by the way)...it mentions 'my i.p. address' which is not correct (thank god), and it must think I'm an idiot...So....any way to resolve this before I trash my favorite browser forever???

Thank you!! I can't believe it was something that simple.. I have no idea how I had those items added on, but I'll make sure to doublecheck them periodically now! Thanks again :)
