Vimium and Vimium-FF are possibly the most popular extensions as of the moment of writing (based on the number of users on Chrome Web Store and on the Firefox Add-Ons website). There are many more available, and most mature browsers have Vi-like plugins. Here are a few more examples:
- Google Chrome also has extensions including cVim or Vrome, that perform a similar function to Vimium, each providing slightly different functionality. Extensions such as wasavi focus on using Vim emulators to edit text areas.
- Safari supports Vimari, a port of Vimium.
- Mozilla Firefox has more add-ons similar to Vimium-FF: Vim Vixen and Tridactyl to name a few.
- Opera supports installation of Chrome extensions.
