I've stopped development of RDR and will provide no further versions. Feel free to take over the project.
Removes Redirects like http://redirectremover.mozdev.org/?www.mozilla.org from Links and Images
It mainly has two purposes:
  1. Speed up browsing by de-proxyfying images and directly jumping to link-target
  2. Increase transparency on some links by showing "real" link-target

It doesn't really increase your privacy. It can, but there are like a dozen ways to circumvent Redirect Remover, so don't expect it to do wonders. If you would like to test your Redirect Remover installation, have a look at the test page with all kinds of links containing redirects, special characters and so on.

Version compatiblity
It seems that you're using an outdated version of Firefox. You should strongly consider updating; otherwise go to the Version History and pick the latest RDR version that supports Firefox

Other versions

Older versions can be obtained via the "Version History". If you want the old highlighting concept, install 1.1.1 from that page.
