It just does nothing. Reproducible: Always Steps to Reproduce: 1. On a page that contains a hyperlink to a document that has a Content-Type header that is defined in the Applications tab of Firefox Preferences to "Always ask". 2. Click on the link, and you should get the dialogue "You have chosen to open...". 3. Choose the option "Save File" 4. Close the tab that had the hyperlink that you clicked. 5. Click OK in the "You have chosen to open..." dialogue. Actual Results: The dialogue closes, silently failing. Firefox does not download the file, and it does not reach the step to ask you where to save the file to. Expected Results: Expected is what would happen if you did not close the tab. You should be asked where to save the file to and it should be downloaded as normal.

Is this duplicate of bug 368759 and bug 262446 ?

I suppose it is a dup of 262446, but 362446's description is when the window closes due to the javascript telling it to close. This description is when you close the tab. But I'm sure the root cause of the problem would be the same for both cases. Also you said in the comments of the other bug, its not seen in Linux, well the problem I'm having here is evident on Linux.

Yes it surprises me. I tested with FF 3.0.18 on Linux. Save file dialog stays for me. But in case of Windows, it is glued up with its parent window. I used FF 3.0.18, 3.0.19 and 3.6.3 to test. But no difference. Common part of all these bugs is if parent window is not open download will get affected.

Updating version and platform based on dupe

On Firefox 6.0 on Mac OS X 10.6.8 : I do the scenario of request bug 682566. I have reproduced the bug. And at the end, I quit Firefox. In my Downloads folder, I find a file "S39d9ES0.exe.part". This is incorrect.
