I have done all I can to set my default new tab page as about:newtab. I've tried to do all the research and change as much as possible, removing any inking of Yahoo from Firefox and yet I still end up with that damn Yahoo search page every single time I open up a new tab. It's bad enough that the "top sites" have been reduced down to micro size buttons. Now I can't even access them in the most simplest of ways. Thanks for ruining all that was good.
