Every website I try to visit with Firefox produces a page which reads "Suspected Phishing." And when I click on "Ignore and proceed" I am taken to a blank webpage. Each web address in the URL field reads "SmartDirect.de." Firefox has thus, for me, become a useless browser. Is there anything I can do to fix this problem with Firefox? In answering my question please bear in mind I do not have a PhD from MIT and am not an expert in computer science.
