Description

[Eric]

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; GTB0.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
Build Identifier: Firefox 4.0

After upgrade from Firefox 3.6 to Firefox 4.0, our internal webpage that was Joomlar 1.5 based would encounter the following error:
Illegal variable _files or _env or _get or _post or _cookie or _server or _session or globals passed to script.

Tried with Google Chrome to reach the same Joomlar 1.5 internal webpage, fine.
Tried with IE8 (8.0.6001.18702), same error as shown above.
Use Firefox 4.0 to reach our internal webpage that is not joomla 1.5 based, fine.

Downgrade Firefox back to 3.6, reach the same Joomla 1.5 page, fine again.

Reproducible: Always

Steps to Reproduce:
1.Upgrade Firefox from 3.6 to 4.0 after download from the website.
2.Try to reach known Joomla 1.5 based website.
3.If encounter the error as in descibed in the detail area, downgrade Firefox back to 3.6 and try again to reach the Joomla 1.5 based website again to see.
Actual Results:  
Illegal variable _files or _env or _get or _post or _cookie or _server or _session or globals passed to script.

Expected Results:  
It should work fine to reach Joomla 1.5 based webpage fine as with Firefox 3.6.

Our page was built based on Joomla 1.5 and use internally of our company, so could not get to it from outside of our company.

It looks like it is coming from this joomla function - http://api.joomla.org/__filesource/fsource_Joomla-Framework_Environment_joomlaenvironmentrequest.php.html#a516

Thanks for the comment Jonathan.  The thing is with the same Joomla 1.5 function, with Firefox 3.6.16 works fine, but once upgrade to Firefox 4.0, then this error displayed.  Then I have to downgraded back to 3.6.xx, from Firefox 4.0 in order to work again.  Sorry, our site is internal, otherwise will let you experience it.  The weird thing is the exact same issue also happen to IE8, but I didn't file bug for IE yet.
I use google Chrome, works fine with with our internal site that built with Joomla 1.5

Thanks for the comments Matthias.  

I don't have energy to try the upgrade and downgrade on Firefox anymore, but already experience it the whole process once as described in the above reply.

I tried "Ctrl+Shift+Del" on IE8, didn't help after deleting or clearing the cookies and disk cache.  The issue still there with IE8 since I don't have IE.x to downgrade and upgrade with.

I am happy with Firefox 3.6.16 to access our internal website now, and that is good enough.

With Firefox auto updated to 3.6.17, the same issue had happened as described when upgraded to Firefox 4.0 manually.  
Can't believe it I have to downgrade it again to 3.1.16 again with Firefox.
