Whatever7276...please use the following links to fix your access to LinkWalker. I have done this myself (using info from the first two links), and it works great! I have also used the methods to update other non-working add-ons. I have not used the last link, but included it just in case you wanted to try it.

Thans again PJC.Addons! I continue to find LinkWalker to be the best add-on for its purpose! Simplicity is best sometimes!

This review is for a previous version of the add-on (1.0.1).  This user has other reviews of this add-on.

Thanks for your review - much appreciated.
LinkWalker has been upgraded to Firefox 4, 5, 6, 7 and 8, and should be available shortly.
Thanks again!
