I recently upgraded to Mozilla Firefox 4 and now my browser is running really slowly, so I would like to uninstall it. I go to control panel > programs > programs and features. And I clicked uninstall and nothing happens. Also I’m in the process of cleaning my PC from spyware, key loggers, infections and whatever else that had my PC moving at a snail’s pace. I purchased spy doctor and registry mechanic I would like to know what more can I do to protect my computer. So how can I get Mozilla Firefox to uninstall on my computer?
