Many of us have multiple websites that we like to visit when we first open our browser everyday. Wouldn't it be nice if you could set more than one homepage in Firefox? The good news is that you can!
Just go to Tools/Options/Main in Firefox and in the homepage field, enter your favorite webpages separated by the "|" vertical separator (without quotation marks). The next time you open your web browser or click on the Home button, all the pages you've set up will open in separate tabs.
