This is the Cryptofox add-on. It contains:
- A program (lib/main.js).
- A few tests.
- Some meager documentation.
- GnuPG
- libgpgme11
If you are on 64-bit linux, but running a 32-bit firefox, you may run into the issue where the libs cannot be loaded. If this is the case, you need to use getlibs to install the 32-bit versions. For example, if gpgme cannot be loaded, you might do:
Install the 32-bit version:
$ sudo getlibs -p libgpgme11
Make a symlink from the library to the name the plugin is looking for:
$ cd /usr/lib32
$ sudo ln -s libgpgme.so.11 libgpgme.so
