As we count down towards to release of the much awaited “Firefox OS” aka “Boot 2 Gecko”, every one is eager to get a piece of the action. Now, as we wont be able to get the devices which will be running this magnificent OS or do not want to flash the Nexus’s and Samsung Galaxy’s to get a feel of what is Firefox OS all about; don’t be disheartened. You can get one of the desktop builds, either for Mac/Windows/Linux and experience the OS first hand.

Now, there are many places where you might be able to get the information as to how to run these desktop builds on various operating systems, especially on the official Mozilla b2g/gaia wiki. So the effort in these blog posts would be to simplify and demonstrate stepwise procedure as to how one can get started.

The following post is for anyone with Mac operating system. Subsequent posts will contain Windows and Linux tutorials as well.

    export WORKON_HOME=$HOME/.virtualenvs
    source /usr/local/bin/
  • Run the following command:
    $source .profile
  • Now you are ready to make virtual profiles by:
    $mkvirtualenv <name_of_env>
