Firefox has an "Automatically download and install" option for itself. However, for add-ons, Firefox can check for updates automatically, but it cannot automatically install updates without prompting. I'd like to have an option to download and install all add-on updates without prompting, just like updates to Firefox itself. Ideally I'd like to see this on by default, but I could live with having to turn it on myself. This would help when supporting novice computer users, as it would reduce the number of unnecessary prompts they have to deal with, while ensuring that their systems stay up to date.
