So I'm using Firefox. And I Google Search. And the searches come up. And I click one. Nothing happens, well that's a lie. It pretends to load the page. I left it for an hour. Still nothing. I delete cache and cookies, reset computer, try again, un+re stall. Still there. Is there something up with Google?
Are you using any add-ons with your firefox that are disabling Google? Sometimes Firefox add-ons such as a yahoo toolbar tend to interfere with things.
