From Merci Chao:
After installing Personal Menu, "Menus Toolbar" is available in Toolbar Context Menu, and you may hide it to save the space of browser. Then you may open Personal Menu Option panel to gather all useful commands into "Menu Button", and pleace it wherever you want; or you may add the items you want in Toolbar Context Menu.
When Menus Toolbar is hidden, although you may add "Bookmarks" and "History" inside Menu Button, it become inconvenient to access them. Therefore, here are also "Bookmarks Button" and "History Button". You may also set what happens after you middle / right-click on them, like open Bookmarks Sidebar after middle-clicking Bookmarks Button, and Undo Close Tab after right-clicking History Button.
What's new in this version:
Version 5.1 has improved compatibility and supported Firefox 16.
