Vimium is a Chrome extension that enhances web browsing by allowing you to use Vim-friendly key bindings to navigate pages. It has also been ported to Firefox under the name Vimium-FF.

Vimium is available from the Chrome Web Store or at https://vimium.github.io. Vimium-FF is available from https://addons.mozilla.org/en-US/firefox/addon/vimium-ff.

For instance, if you hit f, Vimium will highlight every link on a page with a letter or a combination of letters (similar to the way EasyMotion works in Vim). This is shown in the following screenshot:

Pressing the right combination of letters will open a link, or place your cursor in a text box. Vimium supports visual selection to copy text without using a mouse: hitting v once enters a caret mode (where you can move the cursor around the page), and hitting v again enters a visual selection mode. Most movement keys familiar to you from Vim work in these modes, as shown in the following screenshot:

Once you select the text in a visual mode, press y to copy (yank) it.

Vimium also provides an omnibar for switching between tabs (T), opening URLs/history entries (o/O), and bookmarks (b/B), as shown in the following screenshot:

Finally, help is available at the press of a button. Press ? to open a help page and learn more about Vimium features, as shown in the following screenshot:
