At my last organization, we included Mozilla Firefox in images for deployment to all the computers for the sake of having an alternative browser since Firefox 2. Before I left, there were already talks about removing Firefox and discontinuing support for it as an IT department. It increased overhead and problems with user support (another thing to cause issues, teach users, and ensure it’s backed up) while not proving to be that worthwhile as pre-launch update checks confused users and made new computers seem slow. I was even able to develop a method for deploying Firefox 3 to the entire organization but the method didn’t work for long outside of that window.
