One of the great changes coming with SharePoint 2010 to the end user is a wider choice in browsers and platforms. Next to its latest Internet Explorer 7 and 8, Microsoft now supports Firefox 3 and Safari 4 – and not only on Windows, but also on the Mac (and as far as I know Firefox on Linux is supposed to work as well).
If you are developing SharePoint interfaces or you are an administrator responsible for your company’s SharePoint environment, here is one thing to consider when planning the upgrade: SharePoint 2010 and Internet Explorer 6 don’t go together well – or as Microsoft puts it: this combination is not supported.
If for some reason you want to leave the (initiation of the) browser upgrade in the hands of the users, Randi Disgrill has an easy way to show users a message that makes them aware of the need to upgrade. Two words of caution though: I recommend not using this solution, when the users actually cannot upgrade the browsers themselves (huge potential for massive frustration knocking at your door), and I definitely would add a “do not show this warning anymore” option or show the message only once a day.
