Vimium/Surfing keys equivalent for Tor Browser?

Hi,

Does there exist a tool that gives you vim key bindings in the Tor browser?

Unless it has been changed in the last couple of years, Tor Browser is based on Firefox, so any Firefox extension would work. However you should really think twice before installing any extensions in Tor Browser. Quoting what the authors say on its website:

We do not recommend installing additional add-ons or plugins into Tor Browser

There are three reasons for this:

  1. Extensions can introduce security vulnerabilities.
  2. Extensions can potentially bypass Tor.
  3. In some instances websites can see your list of installed extensions, or at least infer it. Running something like Vimium on top of Tor Browser makes your browser’s fingerprint virtually unique, greatly reducing anonimity.
