As noted by Jamie, accessible labels for richlistitem elements come from the label elements that have value attributes within them. In bug 1608202, we accidentally reused the same fluent message for the buttons in about:downloads and the library download view (DownloadsViewUI.jsm) and the context menuitems that do the same thing. This meant that those menuitems gained a tooltip they shouldn't have, and the buttons gained a label and accesskey they shouldn't have. The latter caused the accessibility regression described in the bug. This patch separates out the two usecases for the same string. I also checked the other l10nIds used in DownloadsViewUI.jsm, and as far as I can tell this is the only one that is reused in this way.
