Tabs changed the way we browse the web. No longer do you have to open new browser windows to view additional content. You can just create a new tab and enter a URL or search term. Most browsers even let you right-click on any link you find on a web page and open it in a new tab.

But when you open a new tab the old fashioned way by clicking the "new tab" or Ctrl+T keys, you're presented with a blank screen that honestly doesn't do you much good. So the folks at Mozilla are thinking about ways to make new tabs instantly useful. One idea, which you can see detailed above is to throw a search box onto every blank tab, since there's a good chance you're opening a fresh tab to search for something.

It doesn't stop there though. The conceptual search box would be linked to the Firefox 3 Awesome Bar, which means it has access to your web browsing history and can offer recommendations for sites you've recently visited as you search. And if you highlighted and copied some text on another web site before opening your fresh tab, this concept design would try to detect what kind of text you copied and offer even more useful suggestions. For example, if you copied a date, you might see a box with the option of adding the date to a calendar. If you copy an address, you might be able to map it with the click of a button.

After the jump, check out another concept from another Firefox developer. Either one of these ideas could find their way into future versions of the web browser.
