Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

We have Firefox ESR at my company and the 68.12 version is supposed to update to version 78 but it fails.
If I click on "about firefox", it downloads the latest version but then fails to install it and a popup asking to update manually appears.
Obviously it's not acceptable since the users are not admin.

Not the first time I've seen this kind of problem in the past.
This bug report is the closest I've found for the previous version : https://bugzilla.mozilla.org/show_bug.cgi?id=1566478

Nothing but problems with the auto-update module...
