$HOME/.conkeror.mozdev.org) for the Conkeror

You can copy and modify it under the terms of the GNU GPL version 2.0 or higher as published by the FSF.
The code is available via git on my own Git server.
There are mirrors of the git repository at GitHub and at Gitorious.

Conkeror's git repository is at repo.or.cz, but there's also a (possibly outdated) copy at GitHub for those who like GitHub.
