Firefox can be configured to automatically check for updates to the application, search engines, and any installed add-ons. This article shows you how to configure Firefox for automatic updates and to manually check for updates, if desired.
Automatic updates
By default, Firefox is configured to automatically check for updates.
Minor updates will be downloaded in the background and installed when you restart Firefox.
If an update has been waiting to be installed for more than 24 hours, you'll see a notification with the option to restart Firefox and install the update.
