Firefox keeps changing search engine

Okay, I think this is the right forum.

Whenever I type in something in the address bar, like "java tutorials" for instance, it will take me to these results. It's a custom search setup.

Here is what's my current search engine (about:config - keyword.URL)

http://www.ufsearch.com/search/?ie=U...ient&gfns=1&q=

Now, I don't want that, I just want the normal google search results, but every time I go into about:config and change it manually, it switches back to this weird custom site.

I'm thinking it's an add-on, but I pretty much disabled all of them that I thought were doing that. Maybe it could be a plug-in, I don't know.

Does anyone know what could be doing this?

EDIT:

Um, I searched and found this. I'm reading it and hopefully it gets down to fixing it.
