My Clean Bookmarks v0.5.42resigned1
Add a button to popup your bookmarks. Just a simple list without any decorations, only useful information you're needed.
But you can customize look of the bookmarks list as you want — just go to an add-ons settings page and edit my default `css`-style. You need to set in settings of the add-on (Ctrl+Shift+A) a root folder for showing it.
