Want a taste of what Firefox 3 new themes may bring? One of the expected updates is an integrated menu of visited sites between the back and forward buttons (available on hover only for Mac) instead of separate history menus, in a way similar to Internet Explorer 7. And that’s precisely what this extension is about.

Unified Back/Forward Button is a Firefox extension developed by zeniko, that replaces the back and forward buttons with a single one. A unique tab history menu shows pages visited before and after the current one which is highlighted.

It is completely unobtrusive and has no options to tweak at all. It delivers a more streamlined tab history navigation and lightens the default toolbar layout, two reasons for doing this for the default themes.

Get Unified Back/Forward Button from Mozilla Add-ons.
