I recently downloaded a program called PDFlite to view PDF files. It appears to have changed some settings on my Firefox, which I did not permit it to do. I got on today and there was a Bing toolbar, which I disabled no problem. But now when I open a new tab, it goes straight to the Bing search engine, rather than the blank page where it used to go. This is ticking me off. I hate Bing. I've checked my addons, and there are no new addons added by the program. I can't figure out what's going on. Please help!
