Rated 5 out of 5 stars

Awesome...just the addon I needed.
Just one thing though...after enabling this, the web history in Google cannot show which links I clicked from the search results. Is there any way to fix that?

This review is for a previous version of the add-on (1.4.1-signed). 

The link mangling is how Google tracks which links you click - you can either have web history or proper links, not both.
