# The extensions listed here are no longer supported, these pages are just maintained for historical reasons!

This extension allows you to change the update channel your application receives updates from. If you don’t understand what this means then read about update channels.

Be warned, this extension will allow you to change to an unstable update source. Unless you know what you’re doing I suggest you don’t use it. If you lose all your data because you accidentally update to an unstable version then don’t come running to me.

Please note that Mozilla do not provide automatic nightly updates for users of localised builds. Until those are provided this extension can only help you switch between the beta and release channels for such builds.
