Rated 5 out of 5 stars
A must have add-on. It is similar to the "omnibar" in Google Chrome, but it has the potential to be even better.
However, it is missing customizations:
- Adding/Removing categories
- Adding sites to a categories
- Disabling the tooltip ("Press tab to search the web: …")
Also, the hyperlink color seems to be not adequate to the standard firefox theme.
Finally, I didn't find out how to "show" a category (after using the "hide this category").
