Set Your Firefox Homepage to Multiple Tabs

With this tiny Firefox feature, you will be able to set your default homepage to multiple pages which will open in different tabs. All you have to do is add this symbol, “|”, in between your websites. This is how it should look…
“www.digg.com|www.espn.com|www.facebook.com”
You can add as many or as little number of sites as you would like.

This will also go into effect whenever you hit the home button on your browser. Some of you might have already known about this, but it’s news to me.
