I down loaded something called White Smoke to help my writing quality. I hated what it did to my computer, and completely removed it. Well: my Mozilla Firefox stopped working the next time I used my computer. At the start-up, I would get Firefox Google and NOT my usual Mozilla Firefox browser and everything else. I have tried everything: restore, go back, new Mozilla Firefox browser downloads, new profile, old profile, troubleshooting: nothing works. All I get is Firefox Google ready only to do a Google search. No Browser!
