cVim AFAIK implement the command line mode by injecting the command UI iframe and key binding events to every webpage as a content script. It works, but still less than ideal than what VimFX is trying to do by binding the shortcut globally. There's also an ongoing discussion to try to port Vimperator to WebExtensions[1], which having everything as content script might be one way to do. However, it still doesn't give an ability to modify the UI as XUL/XPCOM Vimperator does.
