Hotmail - Chrome needs upgradation

I usually use my firefox browser for accessing my hotmail account (yes I still have one, inspite of having a gmail account), recently after installing Chrome, I accessed my hotmail account, I was surprised to see a message asking me upgrade the web browser, does it mean chrome developers didnt take this into account?? or is this a way for MS to get back at Google for stepping into the browser territory :)
