I did not use an old Firefox browser.
This is the solution I found from the Internet, and I tried.
Type about:config for the address.
Remove the value of the general.useragent.vendor so it's blank.
After signed in, I switched to Full Version
Here I can switch to the full version of Hotmail successfully.
I see that Windows Live Hotmail is not good for small-size window.
Here the snapshot when I maximize the window.
Opera, that has no problem on using full version of Windows Live Hotmail, also has problems with small-size window like this..
Even using Internet Explorer on my Windows XP does not solve the problem. So it's about the design of Windows Live Hotmail.
