Seems I misunderstood one of the review comments in bug 816254 :-S I've verified that this does indeed work, however I notice that when deleting a download (in this case the only in the list), it seems to try to remove the same item twice: Downloads: A single download with id flzsqcFmXrNc was removed. Downloads: A single download with id flzsqcFmXrNc was removed. Downloads: A download data item was removed. Downloads: Removing a DownloadsViewItem from the downloads list. Downloads: The downloads item count has changed - we are tracking 0 downloads in total. Downloads: Removing the panel's hasdownloads attribute.

There's something to fixup there, but as you said it's unrelated to logging.

Tested using the latest hourly from m-c cset: https://hg.mozilla.org/mozilla-central/rev/a0c57dffd179 While this bug is 'FIXED', download was removed from the Panel & History Library there is still this error in the Error Console: Error: Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDownload.remove] Source file: resource://app/modules/DownloadsCommon.jsm Line: 1463 aDownload.remove(); Win7 x64

I got same Error as the one in Comment 0 on Nightly (2013-02-17) on Windows 7 x64 but I can confirm that the fix is verified on Latest Aurora 21.0a2, "remove from history" works as expected! Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130221 Firefox/21.0(20130221042021)
