User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.3a4webm) Gecko/20100518 MozillaDeveloperPreview/3.7a4webm Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.3a4webm) Gecko/20100518 MozillaDeveloperPreview/3.7a4webm Apparently, a long row of alert()s in JavaScript can stop users from being able to close a browser tab. Reproducible: Always Steps to Reproduce: 1. Browse to the given site [not safe for work] 2. Attempt to close the tab 3. See how the script prevents you from doing that Actual Results: I cannot close the tab because of some lame script Expected Results: I can, despite the message box, click the tab close button AGAIN if I want to force-close it, which would then close the tab and the message box instantly and terminate the script.
This is a dup of bug 61098, but as it looks like that one won't be implemented I'm going to dup this against bug 59314.
