Vim fans will be delighted and amazed for knowing this the first time: Vimperator is the plugin for Vim-like behaviour on Firefox. It’s the original one and it focuses on usability. Following the hints with f is great! Here’re some useful keystrokes:

• To open a link in a new tab, type F and follow the hints
• To move the [num]-th tab, type [num]gt (applicable to Vim also)
• To go to another page, type o
• To go to another page with similar URL, type O
• To open another tab, type t
• To open another tab with similar URL, type T
• To open another window, type w
• To open another window with similar URL, type W
• To copy the URL of the current page (including “#*”), type y
• To copy the URL of the targeted link, type ;y
• To copy the current selection, type Y
• To copy the labeling text of a link, type ;Y
• To disable Vimperator for one instance, type i
• To toogle Vimperator, type <S-Esc>
• To move the last edited text field, type gi
• To open Vim for editing input in a textfield/textarea, type <C-i> in insert mode
• To exit the insert mode of a textfield/textarea, the key is the same as the one you use for Vim.
• To enter the insert mode of a textfield/textarea from the normal mode, either follow the suitable hint or use c to re-enter there (may fail and enter into the caret mode).
• To search the history, type :hist [anything]
• In a pop-up browsing history list, press <CR> and ;o to follow a hint. You can type more to filter the suitable one. Typing a capital ‘O’ instead of a small letter ‘o’ gives you :open [wanted_link]
• To view the previous browsed page, type H.
• To view the next browsed page, type L.
• To go to the home page, type gh.
• To view the home page in a new tab, type gh.
