User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b3pre) Gecko/20081205 Shiretoko/3.1b3pre

Yahoo mail will not let you use their newer (AJAX) interface if you are using the Firefox 3.1 beta.  They block it as an unsupported browser.  Setting the user agent string to the string for older versions of Firefox makes mail work perfectly.

Reproducible: Always

Steps to Reproduce:
1.  Run the latest 3.1 beta
2.  Go to mail.yahoo.com  (it may help to delete your cookies for mail.yahoo.com if you have any.)
3.  Log in, and attempt to use new mail interface
4.  Get a message from yahoo saying the browser is blocked because it is unsupported.  The message suggests that you use another browser, and gives you the option of using mail with the old interface.
5.  Switch the user agent string to that of an older version of Firefox (say, 3.0.4).
6.  New yahoo mail interface works perfectly.
Actual Results:  
Get a message from yahoo saying the browser is blocked because it is unsupported.  The message suggests that you use another browser, and gives you the option of using mail with the old interface.

Expected Results:  
Should be able to use Yahoo Mail with the new interface.
