Firefox:Download Manager:Scratch Pad

When the user is downloading, we should only display a link to pause a downloading entry. The cancel link shouldn't be displayed on a downloading entry since the user might accidentally click on it and cancel the download. Instead Cancel should only appear on a paused entry.

However, all of the download control commands (pause/resume, cancel and restart) should be available on the context menu and the user should be allowed to select multiple entries and apply actions on them.
