Error: ReferenceError: animateCloseAlert is not defined

First, verify that you have the last version of extension : since AMO
makes reviews, it can take some time before an issue is fixed and a new
version released, and it's validation by the AMO team.

(Verified. I even installed the latest download from here in case it had any 
difference)

What steps will reproduce the problem?
1. Install the extension in Firefox Aurora (I didn't try any other version)
2. Enable notifications in Gtalk
3. Wait for someone to talk to you, or send more than one message at once, or 
something (doesn't always happen)

What is the expected output? What do you see instead?

It should animate the closing of the notification, it errors instead, showing a 
modal messagebox (log below).

What version of the product are you using? On what operating system?

v1.2, on Firefox Aurora (21 alpha), on Windows 7 x64

Please provide any additional information below.
