Firefox: it's just too darned expensive

This could be possible with Firefox too(I don't know), but I would require a specific tool to be developed, tested (by Mozilla for example) and LEARNED by the admins.
The tool itself needs to be deployed...
First result for "Group policy Firefox"
Plus the cost of training IT people to install Firefox across thousands of computers (you didn't think they'd install it one-by-one did you?).
Etc, etc.
(With the notable exception of lacking the Canvas element. Seriously IE team what is up with that?)
Look, I'm no fan of IE. But if Firefox advocates want to make headway in business and government arenas they need to stop making BS arguments and start looking at the facts. Saying there's no expense to switching to Firefox (on a mass level) or that IE development is a big money drain are both so easily discredited that they make the overall argument (that Firefox is better) look invalid. Because they make those making the argument look like they're just acting of irrational hatred of IE rather than actual facts.
IE actually saved me some time the other day. A client is using TinyMCE and wanted spell-check enabled. I thought this required a PHP script on the server (which is not going to happen, our infrastructure is not set up to run PHP), and that I was going to have to port that script to Perl. Turns out it can use IE's built-in spell-checker instead. Since the client only uses IE, the problem was solved.
This does not make up for the thousands of hours I've spent on things that work great in Firefox, Safari, and Opera, but immediately kill all scripts in IE. (The error messages are crap, and the debugging tools don't work. Nice!)
Even just testing all the apps on all the sites to find out if they are compatible with Firefox costs time and money.
Many organizations won't even consider a switch unless it works with their tools.
As many big organizations, the DoS is dependent on Windows. The harm (depending on a single vendor solution) has already been done and it will take some steps to undo.
BTW, I would fire a developer who does a web app that only runs on IE, even if IE is the only browser mandated by the organization. Stupid rules are no excuse for employing incompetent people on public money.
Besides, an organization is and far more likely to switch browsers than to switch OSes because changing browsers is a less dramatic change that is less disruptive to their old way of doing things.
Or, turn it around: would you insist your intranet apps support IE 6, even if using IE 6 is forbidden by IT policy?
The long term expense of doing many things is often less than doing nothing. Otherwise, no one would ever do anything.
A myopic bureaucrat? Naaa...
