With new update NoScript icon has again disappeared! Rated 3 out of 5 stars

I like NoScript. I don't find it difficult to use at all and have no popups from it.
But I get tired of periodically losing my icon from the top of the page! I lost it AGAIN yesterday! How do I get it back? I've tried everything in "options".

This review is for a previous version of the add-on (5.1.1).
