Weird,
I've checked and it gives me color managment like in Firefox.
That was not the case in the I.E previous version.
Also, think that this browser color managment issue is IMO a little over concerned in the sense that you may want to see your pics with c.m but you can not control the users browser.
As soon as you put pictures in internet, you have to accept that 60% of the people will not see properlly the colors and there is nothing you can do about that.
(without talking about screen (un)calibrations etc...)
Don't worry too much about the color profiles in browsers. Only the photo/videographers have their screen and browsers properlly setted.
