Adds a Bug to my Sidebar Rated 1 out of 5 stars

I'm using Firefox 15.0.1 and All-in-One Sidebar 0.7.18
"Bookmarks Sidebar Scroll Retainer" seems to do what it should after a search: If I write something into the search and then delete the search phrase, it scrolls to the right position.
BUT: If I change between something else e.g.: Addons, Info,.. and back to Bookmarks the word "Search..." (on my installation it's "Suchen..." because my language is set to German) which, should be gray and not really there (if you click it, it should disappear), is a normal text and filters the bookmarks. If I clear the search all bookmarks appear again, but the old position is lost.

Sorry, but this way it does more harm than good.
