Answer 1

Something changed your home page. If you prefer the built-in home page, you can delete the ominent address in the following dialog, and use '''about:home''' instead.
* [[Startup, home page and download settings]]
* [[How to set the home page]]
But... this might not stick if whatever switched your home page is still on your computer. Please also check:
(1) user.js file
This is a file that Firefox reads at startup which overrides your previous session settings. To remove this file, see the steps in this article: [[How to fix preferences that won't save]]. Note: If windows does show the .js on files like prefs.js, sessionstore.js, and user.js, you can turn off the hiding of file extensions using the methods in this article: [http://support.microsoft.com/kb/865219].
(2) Windows Control Panel, Uninstall a Program
Click the "Installed on" column heading to bring the most recent infections, I mean additions, to the top. If you recently installed some free software, it may have been bundled with whatever is responsible for changing your home page. Try to remove unwanted software here.
And... hopefully that will cure it! If you want to mop up a bit more, check out the cleanup tools other Firefox users have found helpful, in this article: [[Troubleshoot Firefox issues caused by malware]].
