VimFx is a Firefox extension which adds short, Vim-style keyboard shortcuts for browsing and navigation, for a near mouseless experience.
VimFx is made by these awesome people.
Before installing VimFx, make sure LegacyFox is installed. On Linux, you can issue the commands below; on other operating systems, you can copy the files from the LegacyFox repository into your Firefox installation directory.
git clone https://git.gir.st/LegacyFox.git cd LegacyFox sudo make install # set DESTDIR= for custom install location
Even before Vimium there was Vimperator for Firefox. In my opinion, Vimperator has too many features and aggressively changes the default Firefox appearance and behavior. Vimium is exactly what I need in terms of added functionality, but for Chrome. That’s why I decided to develop a similar extension for Firefox.
VimFx will be nice to your browser and to your habits. Promise.

VimFx has concise shortcuts for most commonly performed actions. Many simply invoke standard Firefox features. That is preferred over re-implementing similar functionality.
Press f to mark links, text inputs and buttons on the page. Then either type the hint or the text of a marked element to click it. This command has many variations, for example to copy links or open them in new tabs.
Search with / and cycle between matches with n and N.
Open a new tab with t, close it with x. Reopen it again with X. Switch between tabs with J and K, or some of the several other tab commands.
Scrolling left/down/up/right: h, j, k, l.
Top/Bottom: gg, G.
Page up/down: space, shift-space.
Half a page: d, u.
Use Caret mode to copy text without using the mouse.
There are of course many more shortcuts! Press ? to see them all, and then / to search among them. Click on a command or open VimFx’s options page in the Add-ons Manager to customize the default shortcuts.
You can temporarily disable VimFx by using Ignore mode. Press i to enter it, and shift-escape to exit. Use the blacklist to automatically enter Ignore mode on specific sites.
There’s also an article on ghacks.net which is a good introduction.
