Hi oldman12, Sorry you are having problems. You will not have got adware from a Firefox update unless you are using some none official site that bundles Firefox with adware &/or modifies it (possiby illegaly). You did not provide full troubleshooting information. You did provide a plugins listing whilst posting the question. Your plugins list includes * MindSpark Toolbar Platform Plugin Stub for 32-bit Windows That is probably not good. It is probably part of your problem. This guide may help you with the mindspark problem. * http://malwaretips.com/blogs/pup-optional-mindspark-removal/ It also offers some advice,and may at the same time help with other malware or adware you may have. * Also see [[Troubleshoot Firefox issues caused by malware]]
