For places like yours, what we need is a web-browser (probably Webkit/Gecko) that works off a single executable, does not require installation, does not need admin privileges, has no library files, no large caches, does not save to registry, does not have addons, does not write anywhere except for a single file in temp folder. It should check for an admin config file in a specific read-only location and save user config/bookmarks to user's "Document & Settings." If such a browser existed and explicitly mentioned the above restrictions/features, it would be trivial for most IT departments to put the browsers's .Exe in a read-only network share and put an icon for it on every user's desktop. The problem is that other than IE, every other browser is a pain to setup on a Windows network. I have Chrome installed on a couple of Terminal Servers and it took almost two full days to make it put the cache files in the right places. And I had to write my own script to empty the cache because there is no easy way to automate it. On the other hand, it is very easy to deploy IE7/8 but since many intranet sites have been custom written for IE6, it is not possible to upgrade to other versions of IE. Things break and it's very costly to fix them. I've seen a $400k software system that only works in IE6. The pages don't even load in IE7+ or other browsers. The upgrade to a version that is IE7-compatible is $300k. So for the IT department, it's either IE6 or $300k. Management does not care and should not care about IE6 working for all sites. They need IE6 to work on this expensive piece of software that runs their business. Despite what people here on HN say, IT departments don't mind users using alternate browsers. Their problem is that Firefox, Chrome, Opera, and Safari aren't easy or even possible to setup in a server environment like IE is. Depending on which user belongs to which department and logs in from which location, I can configure their IE to automatically set homepage, proxy settings, privacy/cookie settings, and lots more. Forget features like these, with other browsers, I don't even get to set the location of the config files and cache folders. When you have 100 people logging on to a terminal server, you need to be able to configure these things or the entire server goes down because some user downloaded a partial 2GB file which is still in their cached folder and now the server is trying to save it back to their user-profile folder. TL;DR version: Give me a browser that I can setup easily in corporate environment and I will set it up.
