Bookmarks Clean - Detect damaged bookmarks

Terrible plugin. Displays ALL bookmarks, including perfectly good bookmarks, so you have to click through one-by-one to manually verify if they are dead or good, and no way to select/bulk-delete. Completely useless.

I don't see where it's doing anything, it does not appear running. The scroll bar just keeps jumping back to the top, therefore I have no idea if any function buttons are at the bottom of my list of bookmarks.
