It should be noted, that if you disable silent updates, that does not mean that you should not install new updates when they become available.
If you do not install the updates, you could put your computer at significant risk due to potential security vulnerabilities that these updates may be fixing.
With the release of Firefox 12 for Windows, Mozilla has introduced a new feature called silent updates.
This feature will allow Firefox to install updates without first displaying a User Account Control (UAC) dialog.
It is strongly recommended that you do not turn off add-on update checking, as you may miss critical security updates to your installed add-ons.
If you only wish to prevent add-on updates from being automatically installed, you may turn that functionality off from within the Add-ons Manager.
For physical problems -- eyes and color, I want to keep this version and not do any updates ever to it. Update Manager and added to ingnore package --firef0x* 2.
You can disable silent updates using two methods, which are described below.You might even close Firefox and delete/rename this folder. NOTE: Do NOT delete %App Data%\Mozilla as this would erase your Firefox profile including bookmarks etc.On Windows XP you can find the same folder at "%User Profile%\Local Settings\Mozilla".But if you -- like most people -- are using Windows 10 Home, you'll need to use workarounds to stave off Windows 10's aggressive automatic updates.The most obvious -- albeit laborious -- solution is to install updates at times when it's convenient for you.
