SBC/yahoo dsl customers have access to a homepage customizable with different
modules. The module called Today is a Flash module of current events. This
element worked fine with  Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.7) Gecko/20040803 Firefox/0.9.3. It does not work in the default
installation of  Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3)
Gecko/20040913 Firefox/0.10 with a fresh profile, instead the flash module is
overlayed with an upgrade flash message, although I have verified I have the
identical Flash plugin in both versions. With help from Pike, I disabled
document.all in the 0.10 version, and the flash module worked again.

Reproducible: Always
Steps to Reproduce:
1.go to http://dsl.sbc.yahoo.com/   (*see note at bottom)
2.make sure the Today module is included in the page
3.see message to upgrade to Flash 6 or above
4.disable document.all with the following steps:
      a. Enter about:config in the location bar.
      b. Right-click New->Boolean.
      c. Set the name to browser.dom.document.all.disabled and the value to    true.
      d. Restart the browser.
5. Go back to http://dsl.sbc.yahoo.com/
6. See Flash module working 
{*NOTE: You must be a SBCyahoo DSL customer to access this page, however I
created a subaccount for testing purposes if needed, I will PM or email login
and password info if requested. This is a subaccount of my own that I was able
to create as a benefit of premium service, the account is separate from my own,
and will be deleted after any testing or if not needed, however I do not want to
post the info here for obvious reasons}
Actual Results:  
fixed flash module on http://dsl.sbc.yahoo.com/ by disabling document.all

Expected Results:  
Shown Flash module

Although document.all actually causes the page to be read as written by Yahoo
(they "do not support the Mozilla Browser")when read this way it implements an
"If no ActiveX enabled/ then show update Flash Message" which was ignored before
document.all support, so appearing to be a regression. There are numerous posts
in  the forums about this, even though it seems a trivial issue. Other flash
sites on yahoo still work. This thread is a more detailed description of the
problem and solution: http://forums.mozillazine.org/viewtopic.php?t=131149  as
stated in the thread, an option for conditional disableing of document.all would
be appreciated.
