[Mozilla Enterprise] Thunderbird 68.2.0 preinstalling add-ons

[Osdoba, Sascha]

Hi,

until TB version 60.x I could preinstall addons during TB deployment via SCCM per copying to "programfiles(x86)"\thunderbird\extensions\extensionID\" (we use TB x86 on Windows x64)
and I deployed 5 or 6 addons without problems. Now with 68.2.0 its not working this way anymore but I did not find any documentation about a change.

Somewhere was mentioned to deploy it to "%programfiles(x86)%\mozilla thunderbird\distribution\extensions\extensionID\" but that did not work too.

I am trying to deploy following addons (most of them are updated and are known as ready for 68.x):

tbsync at jobisoft.de
de_DE at dicts.j3e.de
@unitedstatesenglishdictionary
dav4tbsync at jobisoft.de
eas4tbsync at jobisoft.de
langpack-en-GB at thunderbird.mozilla.org


Any help is welcome.

Thanks,
