I have a long list of Bookmarks Folders which you scroll down I have arranged them to be in alphabetical order. I want to set up my fire fox so when the list Bookmarks folders using the command of Bookmarks command using the Bookmark command in the upper left top corner of the menu bar I can Press a Alphabetic key like L and it will immediate go to all the Bookmark folds List Alphabeticly that are titled starting with L and so on and so on or if I do this Pressing the V key on the key board it will go to all the folders that are title with a letter V.

If you do not have this feature you should put put this feature into Fire Fox to speak your search for what you want in Bookmarks. Thie scrolling down each time takes a lot of time rather than pressing one alphabetic key to get where you want to go to the name of a bookmark folder.
