Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b1) Gecko/2007110904 Firefox/3.0b1

When trying to use Yahoo mail (new web 2.0 mail client version), you get two errors (shown below), and Yahoo mail becomes unusable:

Error 1:
Yahoo! Mail experienced a login error: 

name:NS_ERROR_DOM_WRONG_DOCUMENT_ERR
message:Node cannot be used in a document other than the one in which it was created
lineNumber:463

(this error is repeated frequently, and the browser becomes unusable until you dismiss it.)

Error 2:
Yahoo! Mail experienced a login error: Login error:
name:TypeError
message:m has no properties
lineNumber:647
fileName:http://mail.yimg.com/us.js.yimg.com/combo?/pim/r/dclient/g/js/core/<random identifier string deleted because it refers specifically to MY mail account - you should be able to reproduce the bug on your account.>

Yahoo mail then pops up a message on the web page itself saying that the page is taking longer than usual to load.  It then loops and the page becomes unusable, and must be closed manually.

Reproducible: Always

Steps to Reproduce:
1. Log into Yahoo mail (new mail client version)
2. Get errors shown above
3. Revert to previous Firefox version to check your Yahoo mail.
Actual Results:  
Popups with the following messages in them:

Error 1:
Yahoo! Mail experienced a login error: 

name:NS_ERROR_DOM_WRONG_DOCUMENT_ERR
message:Node cannot be used in a document other than the one in which it was created
lineNumber:463

(this error is repeated frequently, and the browser becomes unusable until you dismiss it.)

Error 2:
Yahoo! Mail experienced a login error: Login error:
name:TypeError
message:m has no properties
lineNumber:647
fileName:http://mail.yimg.com/us.js.yimg.com/combo?/pim/r/dclient/g/js/core/<random identifier string deleted because it refers specifically to MY mail account - you should be able to reproduce the bug on your account.>

Yahoo mail then pops up a message on the web page itself saying that the page is taking longer than usual to load.  It then loops and the page becomes unusable, and must be closed manually.

Expected Results:  
You should be able to check your mail in Yahoo mail with no problems, as you can in Firefox 2.x.

Works just fine in older versions of Firefox.
