For Firefox 4, we’re thinking of replacing the home button with a home tab. It would be a mini-tab, not taking up any more space than the current home button; it would still be “click to go home”, but “home” would be a special page that is always open in a tab.

If the contents of that special page are useful, this could be a great feature. Because the home tab is part of the browser, like an extension, it would be able to do things that a normal web page can’t, like use statistics about your browsing habits to show you useful things. On the other hand, if the contents of the home tab aren’t useful, then it’s a pointless feature.

Given that… what would you put on the home tab?

That’s the question asked by the latest Mozilla Labs Design Challenge, which is open right now. If you have some ideas, go check it out!
