Rated 3 out of 5 stars

Great concept, but wish it was more flexible.

I'd prefer the the tabs on the left, and URL on the right, as I'm more often looking at the tabs than the URL.

The deal-breaker right now is the search-button going to the google-default; I regularly search directly on wikipedia, amazon, ebay, and custom-search providers [and expect them to open in a new-tab, as per my configs]. While I love the condensed look of Prospector, the loss of specific-search-in-new-tab was a big disappointment.

This review is for a previous version of the add-on (2.1-signed.1-signed).
