## What it is
Vimperator is a Firefox extension (with a companion Muttator for Thunderbird) that makes the browser look and behave like the Vim text editor, providing modal keyboard-driven navigation, hint mode, and ex-style commands. It is end-of-life and stopped working with Firefox 57 due to the WebExtensions migration.

## Use cases
- browse firefox entirely with vim keybindings
- follow links with keyboard-only hint mode
- run ex commands like :back to navigate page history
- make thunderbird behave like vim/mutt
- use a modal web browser

## When to choose
- you are pinned to Firefox 56 or an XUL-compatible fork like Pale Moon, Basilisk, or Waterfox Classic
- you want the deepest vim-like browsing experience including command mode and autocmds

## When to avoid
- you use a modern Firefox release (57+) since the extension no longer works
- you want an actively maintained alternative - consider Tridactyl, Vimium, or Vim Vixen instead
