Steps to reproduce:
- Try and download a .exe file which doesn't exist from your webserver
- Get a "404 Not Found" page
- Press "Reload"
- Get another copy of the "404 Not Found" page (call this "point A")
- Put the .exe file on the webserver
- Reload the page
Result: Firefox silently downloads the .exe file, but the 404 page remains. This scenario is indistinguishable from point A - i.e. it's the same as if the file were still absent.
Expected: page goes back to looking like about:blank, Download dialog comes up, or anything that might tell you that Firefox is in fact doing something and that the file is now there.
This hit me when I was trying to get some access controls right. I was fiddling and fiddling, and still seemed to gett a 404. Then I looked in my Download directory, and found five copies of the file!
Is this only a problem when browser.download.manager.showWhenStarting is false?
I'm not sitting at the relevant computer right now; I'd need to check. The answer is probably "sort of" - in that, if that value was true, you would get a download manager, but the browser window would still contain incorrect information, which is bad.
What should the window contain after the download starts? about:blank?
about:blank would be a reasonable choice. Another option would be a "File download in progress" message. Just something non-misleading.
The "file downloading in progress" indication is given by the download manager, which by default appears when a download starts, so this really is an edge case...
Given that, I think "Firefox should clear the error page for a tab/window if a download is started from that tab" would be a better summary, do you agree?
I don't know what you did to the summary there, but it was horribly broken.
Ook. I cut and pasted what you wrote, but only the second half appeared in the text box, so I pasted the first half in again.
Firefox 1.5 final input line bug. :-(
I bet you're on Linux, as you had an embedded newline in the summary (which caused FF 1.0.7/Win here to truncate the text in the input at the newline). Fun stuff.

I've had this occur with "Show the downloads window when downloading a file" true.
The response page should be helpful even when it's false; I'd like to see an info page showing the download URL, and the same controls as in the download manager for each file, including a link to open the file which would be disabled until the file is complete, as well as a link to the download manager itself.
I think if I was new to the issue and saw about:blank, I wouldn't think it had started downloading.
