How do I edit my Firefox toolbar bookmarks?
In the Firefox Menu Bar, select Bookmarks -> Organize Bookmarks. A Bookmarks dialogue window will open.
In the left sidebar of the Bookmarks window, selecting the History button will display a history of sites you have visited in the main window.
Select Bookmarks Menu in the sidebar to list your saved bookmarks.
To edit a bookmark, select the bookmark in the main window then edit the Name, Location or Tags entries displayed at the bottom of the window (if the bookmark you want to edit is inside a folder in the list, double click the folder and the bookmarks in the folder will be displayed). The More button below the Tags field will reveal fields to enter Keywords and a Description for the selected bookmark.
