I have multiple systems with Firefox (64-bit) ESR 45.5.1 installed. When Update 45.6 was released yesterday, nearly all the systems in my company received a message that the update failed to install. Only a few systems finally installed the update after opening and closing Firefox multiple times. The majority still fail to install the update even after reboot. Can someone point me to a solution?

Some protection programs don't like the update/install stubs. Download Firefox For All languages And Systems {web link}

Firefox 45.6.0 ESR:

Does forcing an update via "Help > About Firefox" work?

Do you offer the update in a special way or is this done automatically via the Mozilla website?


Mote that Firefox 45.6.0 is actually released a few days earlier.
