#Firefox extension

Building the firefox extension requires the Firefox Addon SDK. The easiest way to install this is by cloning [email protected]:mozilla/addon-sdk.git and running source bin/activate in the repo which installs the appropriate environment variables in that shell. Some handy commands to get you started: cfx run in the firefox extension directory will run a profile-less firefox process with the extension installed, and cfx xpi will compile the XPI.
