Firefox only (Windows/Mac/Linux): Firefox extension UrlbarExt adds 7 new buttons to the Awesome bar with a wide range of genuinely useful functionality to power up your browsing experience.

We’ve mentioned this extension before, but it has since updated with more functionality and upgraded from experimental to officially approved by the Mozilla Add-ons site (no longer requiring a login to install). The functionality of the default buttons include, from left to right:

  1. Copy the current site URL or custom formatted URL.
  2. Shorten the URL using your favorite service or right-click for more options.
  3. Search the current site using Google for the selected keyword. Right-click opens a dialog for adding keywords.
  4. Go up one level, or directly to the root of the current site with a double-click. Right-click gives you a list of levels to choose from.
  5. Tag and bookmark the current page from a menu of tags.
  6. Navigate through sequential URLs. (if the URL ends in a number, it will take you to the next numbered URL)
  7. Surf anonymously using online phproxy servers. Right-click lets you view the Google Cache along with other options.

Once installed, the settings panel lets you fully customize which icons are displayed by default or hidden behind the “Grippy”, along with a ton of other options.

This extension is now a must-have in my toolbox just for the tag bookmarking functionality alone. Are there any extensions that you just couldn’t live without? Tell us in the comments.
