When you start your Firefox browser window, it should load to your homepage. If not, there may be a problem. This could mean that your browser has been hijacked. Browser hijacks occur in many ways. Most common attacks happen when you visit a web page and trigger code to download to your hard drive. Do not panic if you have been the victim of browser hijacking. Most hijackers do not want to do anything malicious to your computer but use this as a way to direct traffic to certain websites. Take some steps to fix a hijacked Firefox browser and return your computer to a healthy state.
