Hello! Opening Firefox 65.0 on the first run after following the steps from comment 0, the following messages (see screenshot) are displayed in the browser console:
1557823848286 addons.xpi-utils WARN Add-on is not correctly signed.

Mike, could you investigate and triage wrt our upcoming 67 release next week? Thanks

Flags: needinfo?(mozilla)

I installed Firefox 66.0.5 "de" and "en-US" x64 builds (- set up for Acer distribution) -> I set up the language pack as per instructions in the document from Description -> Perform update (Firefox is updated to 67.0) and then access about:addons -> The Languages section is displayed.
It seems that for builds updated from Firefox 66.0.5, Languages section is correctly displayed.

I've tested on Windows 7 x64 and Windows 10 x64.

Summary of what is happening:

Firefox 62 tries to install the addon from the distribution directory, but it fails because of the signature problem.
Even though the install failed, we set the pref:

to true

Because this pref is set to true, we will never try to install the distribution langpacks again.

Flags: needinfo?(mozilla)

This bug should block 67. We need to do a one time reset of distro addon prefs.

Also we need to fix the bug here:

We should not set this pref if the install didn't succeed.

Attachment #9064941 - Attachment is obsolete: true

[Tracking Requested - why for this release]: This is as major blocker for Acer preloads.

They are already in the store, so we have to figure out how to fix this in an update.

Priority: -- → P1

Mike, this patch is r+, what is preventing the landing and uplift request?

Flags: needinfo?(mozilla)

Worth asking if this is needed in ESR repo or not.
