Status: RESOLVED INCOMPLETE

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/532.0 (KHTML, like Gecko) Chrome/3.0.195.38 Safari/532.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6

Since 3.5.6 window.opener.formname to reference a form from a popup does not work anymore.

The popup window is created using window.open. From this window I use window.opener.formname.textboxname.value="value" to fill a form value, but this produces "Error: window.opener.formname is undefined"

In 3.5.5 (and before) this works flawlessly as does IE, Chrome and Safari.



Reproducible: Always

Steps to Reproduce:
1. Create form
2. Open new window with JavaScript window.open
3. Modify value on inputform on parent window with window.opener.formname.textboxname.value="value" 
4. error message
Actual Results:  
Error message "Error: window.opener.formname is undefined"
form value is not modified

Expected Results:  
No error 
Value modified

Probably broken after security fix (bugid 522430)

Technique works in other browsers and Firefox 3.5.5 and before
