Real find, but far from great. Rated 4 out of 5 stars

This add-on is better than any other findbar extensions. However, you can not use it with locationbar option on. It will interfere with cybersearch and any similar extension.

Also highlighting feature disappeared as well as scrollbar mark. I wish I could get them back.

This review is for a previous version of the add-on (0.11.16).
