Review for MonkeyMenu by Iggy
Rated 5 out of 5 stars
It is a shame that this plugin is no longer being updated. I've not been able to find another add-on that gives me this exact functionality. Extremely frustrating.
5 stars when it did work with SeaMonkey. Zero stars now that it doesn't run in the latest version.
