I can't remove "failed" downloads on my trunk Minefield build from today, by either right-clicking the selected download or by pressing the Delete key. The following exception is thrown: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDownloadManager.removeDownload]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://mozapps/content/downloads/downloads.js :: removeDownload :: line 186" data: no] I'll attach my downloads.sqlite

Worth mentioning, of course, is that these three files are: 1) All the same name 2) Large ISO files (4+GB) of Linux distros The first two I acquired through incomplete downloads; the server returned an error in saving to disk, but succeeded on one, which I downloaded for at least 2 GB worth, before manually removing the other downloads, leaving only those two unable to be removed.

Does it work after restarting?

(In reply to comment #3) > Does it work after restarting? Yes; a datapoint I meant to include.

OK, in that case I know what's up, and this is a dupe...

Cool, thanks! Verified dup
