Created attachment 537456 [details] [diff] [review] patch See bug 662152 comment 2. A simplified testcase would be: gBrowser.addTab("http://bing.com", 0)
Can you please be more specific on how to verify this bug as being resolved fixed? thx
Open the error console and execute this: top.opener.gBrowser.addTab("http://bing.com", 0) You should get an exception telling you that 0 is an invalid argument.
