A Firefox add-on that opens a dialog window that lets you search and load bookmarks
Version: 1.1Bookmark launcher opens a dialog window that lets you search and load bookmarks. Shortcut is F4 and it works almost as Firefox default search in the bookarks sidebar.
Operating System: Mac OS X
The difference is that the dialog window is closed when you press Enter to load a bookmark. And you use Enter to go from the search field to the search results. Ctrl+Enter loads the selected bookmark in a new tab.
