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.

Note: If you use your Linux distribution's packaged version of Firefox, you will need wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager).

Automatic updates

By default, Firefox is configured to automatically check for updates for itself.

  1. When an update is available, the Software Update dialog is automatically displayed. It contains a list of updates for Firefox components that are installed on your system. To begin updating your software, click OK. The new versions of any selected updates are downloaded and installed.
  2. When the install process is complete, you must restart Firefox. To close Firefox and re-open it, click Done.
  3. After Firefox restarts, all updated versions of Firefox components are available.
