|If I understand correctly, you have multiple home pages opening whenever you open your browser. Mozilla is capable of opening a number of 'home' pages when you launch it (I use 3 different ones, then close the ones I do not need at that time). If somehow it saved this setting, just close all but one and go to Tools>Options on the General Tab, click on 'Use Current Pages' to reset your home page. You can leave open a few regularly used tabs and click the same button to deliberately set multiple home pages.|
You have to be a little bit crazy to keep you from going insane.
