A translation service provided by a browser toolbar may be automatically updated. In one implementation, a device may obtain a version identifier corresponding to a first configuration file, stored locally by the device, that includes configuration options relating to a language translation service provided by a browser toolbar implemented by the device. The device may request a version identifier corresponding to a second configuration file, stored at an update server and determine whether the second configuration file is different than the first configuration file. The device may download the second configuration file when the second configuration file is different than the first configuration file may update operation of the language translation service based on the obtained options.
