Another big win for Chrome is that there is no approval process to get on their addon site as opposed to Mozilla. Mozilla can take weeks to months to get out of the sandbox (although to be fair, Mozilla is trying quickly to better the experience with a new self hosting option and making it somewhat easier for users to find sandboxed addons), and unless your addon gets some secondary approval, you need to go through the process again to push up updates.
