User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0b11) Gecko/20100101 Firefox/4.0b11

In Firefox 4.0 Beta 11, attempting to create a modal window raises an "uncaught exception" in the Error Console, which stops Javascript execution.

Reproducible: Always

Steps to Reproduce:
1. Type "javascript:alert('test')" into the address bar
Actual Results:  
Nothing happens on-screen, and in the error console, the following message appears:

Error: uncaught exception: [Exception... "'[JavaScript Error: "winUtils.enterModalState is not a function" {file: "resource://gre/components/nsPrompter.js" line: 424}]' when calling method: [nsIPrompt::alert]"  nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)"  location: "JS frame :: javascript:alert('test') :: <TOP_LEVEL> :: line 1"  data: yes]

Expected Results:  
An alert with the text "test" should show up.

This is the first beta that this bug occurs in. b10 and before did not have this issue.

tested on both mac and linux nightlies, 2011-02-17. Works here.

I just downloaded 4.0 RC 1, and the test case above still fails on my end.

Not sure if it's my environment or not... XFCE 4.6.1. Note that real alerts that have their own window, such as alert()s from the Error Console, work just fine.

Just to make sure nothing weird was going on, I downgraded to 4.0b10 again, and the alert worked just fine. Re-upgrading to RC1 re-introduced the error.

I also upgraded to XFCE 4.8.0, thinking that maybe 4.6 was just outdated, but to no avail. Error is still present.

ccing dolske to see if he can make sense of this. Still works here on OS X. Your window manager shouldn't have anything to do with alert dialogs as they're rendered by Firefox now.

[Justin Dolske [:Dolske]]

You still get the _exact_ same error message? Because it was replaced with a call to winUtils.enterModalStateWithWindow(). [Note longer function name.]

Can you reproduce this with a clean new profile?

Comment 6

[Chris]

On my default profile, yes, I still get the error message.

However, I created a test (blank) profile and my test case worked just fine, no error in sight.

Thanks for everybody's help on fixing this ebkac error.
