Yes; although this ability was used very rarely in public add-ons. > I understand that Firefox nowadays requires Add-Ons to be signed by Mozilla. > How > does that work? Does Mozilla use a code-signing certificate? Yes, but it has to be a specific one - we don't trust just any cert which chains up to a root with the code signing bit. So the addons system no longer (or very soon will no longer) uses the code signing bit in the NSS store.
