How is it that everytime I open Firefox, I get my home page more another blank tab?

After you install a new motherboard on my Dell, everytime I open Firefox, I get my home page more another blank tab. Never happened before. Help!

This problem may be caused by the MySearchDial extension.

You can also check if you have a user.js file in the profile folder to initialize prefs each time you start Firefox.

The user.js file is present than if you or another software has created this file and normally it wouldn't be here.
You can check its contents with a text editor (right click: open with) If you do not create this file yourself.

The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.
