Safari extension to get rid of Google redirect links in search results?
Canisbos has released another extension called gDirectLinks, which is a more efficient subset of LinkThing focused solely on the task of removing the hidden redirects from Google's links. It handles both regular Google search and the more modern Google Instant search (AJAX; most people are using that version these days without knowing it, as it's on by default). It also has the option of re-writing Google Images results to point directly to the image.

It's very important to note that gDirectLinks (and its big brother, LinkThing) is the only extension of its kind that properly handles Google Instant results.

More information is available at the official website. Enjoy!
