I appreciate the support as reflected in the comments below regarding my efforts to get Firefox installed on at least some of the public workstations at my library. The comments support my personal opinion that the open source method of software development is superior to proprietary methods, as well as that Firefox is a more secure browser if users can continue to update the software as development progresses.
My frustration lies elsewhere. I am looking for examples of Firefox being used in an enterprise environment where updates to software must be automatic. My Google searches have led to conflicting evidence. Here's my Furl directory of what I have found so far.

There do seem to be some enterprises who have or are using Firefox, or providing it as an alternative. Some do not wish to be identified because of the threat of reprecussions from Microsoft. There are others who feel that Firefox is not mature enough to be adopted at the enterprise level (particularly because of the lack of ability to automatically push updates). And there are people providing practical "homemade" tools to support enterprise use of Firefox.
Anyone else have a story to add to this?
