Firefox versus Internet Explorer in a Corporate Network

Mozilla's Firefox has become known for it's feature set and lack of exploits(well, compared to IE), and it can be argued that it's the better browser to use at home. In a corporate environment however, Internet Explorer's integration with Windows and other factors can outshine the usefulness of Firefox.

"Two years ago I blogged about a similar subject. I discussed the advantages of Internet Explorer (IE) over Mozilla and other web browsers in a corporate environment. I concluded that IE is by far the better choice. Recently we deployed about 250 new computers and so I considered this question again. Now, Firefox is the main rival of IE. The decision was not so easy this time, but IE won again in the end."
