Rated 5 out of 5 stars

Excellent little Add-on. Restores the original Firefox Update UI to the Help menu. This means updates will not automatically be downloaded upon checking. Asks for user confirmation, thereby giving you the choice to download or not. Extremely useful if you want to back up your Profile first, copy the current application, or wait a bit to see if any problems develop with a new version BEFORE installing. Mozilla should never have removed this.
