One of the questions we get a lot in the beginning of projects is what browsers are supported by Sharepoint, this is usually after the clients demand that the implementation must be supported for all browsers . . . or at least most of them!
Microsoft had made available a compatibility matrix that we all used to support our pains . . . well it seems that this matrix is no longer available and now Microsoft states: “Unless otherwise stated, all browser versions are supported. Period” followed by ” . . .The only browser that will clearly state known limitations is Windows Internet Explorer . . .”
These statements were taken of Kirk Stark post on this subject, that you can find here: http://blogs.technet.com/b/tothesharepoint/archive/2012/04/04/updates-to-plan-browser-support.aspx
I really think these are very good news, let us just see what impacts on already deployed implementations . . .
So all browser latest versions are supported . . . unless otherwise stated, of course ;)
