"C:\Program Files (x86)\Mozilla Firefox\firefox.exe"

Does the Add-ons Manager ask you to take an action, like approving a new installation, or does it just list your existing add-ons?? If it's not there for an obvious reason, have you noticed whether it opens only when you first start Firefox, or does it open in every new window (Ctrl+n will launch a new window)? ''Every New Window'' Your home page setting might have multiple addresses. Each address, separated by a vertical bar ("|") launches a separate tab. To review/clean up your home page setting, please see either of these articles: * [[Startup, home page, tabs, and download settings]] * [[How to set the home page]] ''Only at Startup'' The Firefox icon can be set up to launch specific pages at startup (or more specifically, when you use the icon). To check whether that is set: First, open the shortcut as follows: * 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. You'll see the Target highlighted. On 64-bit Windows, that usually is no more and no less than the following: "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" If anything follows after that, try clearing it out. After OK'ing the Properties dialog, you can test right away to confirm that Firefox now launches only your home page. Either: * double-click desktop shortcut * right-click pinned taskbar icon, click Mozilla Firefox Success?
