actually opened.

2. Click on first link (labeled as "Wrong")

Two 200x100 windows are opened

		window.open('about:blank', '', 'width=200,height=100');
		return false;
	}
//--></script>
<a href="about:blank" onclick="return popup()">Wrong</a>

I've been able to reproduce the problem in second computer with similar specs.
The problem started when I installed this extension:

tabextensions_en.xpi v1.9.2003101801 (latest version)

It can be downloaded from here:

Previous version on the extensin (1.8.2003082001) works fine where latest failed.
Since the bug is most likely on the extension side, I suppose it can be marked
as "invalid" and closed.

 this problem available.)
