This extension provides access to BroadMask features for privacy-preserving communication in Facebook.
To read about the functionality of BroadMask, see http://www.broadmask.de.
In order to build the extension, you need to build the NPAPI-plugin first. Instructions on building it and downloads for binaries is available at: https://github.com/oliverguenther/broadmask-npapi.
Once you've obtained (either by compiling it for your architecture or downloading it) the NPAPI binary, you pass it to the build script:
./build.sh <path-to-npapi-binary>
The Build script compiles the Addon-SDK code (requires the Addon-SDK) and combines the extension and NPAPI plugin into a Multiple Item Package
