I've already disabled all the addons, that's what fixed the big problem (that the browser was getting redirected). But now the problem still persists that typing a non-traditional address (ie xyz.com) into the address bar goes to some custom search.
i just realized a few minutes ago that this custom site does indeed look like it could be from google, just a strange type of it. is there some place in the browser where it specifies which engine to use to search when something it doesnt recognize is put int he address bar?
