Rated 5 out of 5 stars
Disregard my May 20 review.
Fixed by going to another login profile, installing the toolbar and going back to my profile.

I have a failure of the LinkExtend toolbar to show up in FIrefox 4. There is only an empty space where the toolbar should be.
LinkExtend has been no help. Anyone able to restore the toolbar can contact me at email@example.com.
