Does the problem occur in every circumstances where you would expect to see your home page, or only at startup? To test that, try: * Ctrl+n to launch a new window * the home button on the toolbar '''''If those are normal:''''' Check for a hijacked shortcut. Here's how: * Desktop shortcut: right-click the icon, choose Properties * Pinned taskbar icon: right-click the icon, right-click Mozilla Firefox, choose Properties Windows normally will select the Shortcut tab. If not, go ahead and click the Shortcut tab. The Target line should not have anything after this part: * 64-bit Windows, standard 32-bit Firefox: "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" * 64-bit Windows, test 64-bit Firefox: "C:\Program Files\Mozilla Firefox\firefox.exe" * 32-bit Windows: "C:\Program Files\Mozilla Firefox\firefox.exe" If any URLs are listed after that, clear them out and save your change. To test, you can either: * Desktop shortcut: double-click the icon to launch a new window * Pinned taskbar icon: right-click the icon, click Mozilla Firefox to launch a new window If you only get your home page, it worked. You probably need to do the same for your other browsers. '''''If the problem occurs when using the home button as well:''''' Check for an unwanted extension on the Add-ons page. Either: * Ctrl+Shift+a * "3-bar" menu button (or Tools menu) > Add-ons In the left column, click Extensions. Then cast a critical eye over the list on the right and, if in doubt, disable (or remove). Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step. Does that help?
