You do understand that mozilla still could reject certain add-ons, even when only to be signed to be hosted elsewhere, and in fact they do:
>Files submitted for signing will go through an automated review process. If they pass this review, they are automatically signed and sent back to the developer. This process should normally take seconds. If the file doesn't pass review, the developer will have the option to request a manual review, which should take less than two days.
Right now, the automatic signing will probably only fail if malware is detected. The "Right now" part is what worries me a bit, tho.
