We are deploying the latest Thunderbird updates (102.15.0 and 115.2.X for x86 versions), and in most workstations, after the update, the application stops displaying emails and remains with a blank main screen. The computers already have configured email accounts in use, and since users do not have administrator permissions, the update is distributed through a third-party application that runs a script silently. This script copies the files locally and runs the command "Thunderbird Setup 115.2.2_x64.exe" /s /INI="thunderbird.ini." In the "thunderbird.ini" file, the following is configured: [Install] QuickLaunchShortcut=false DesktopShortcut=false MaintenanceService=false StartMenuShortcuts=false PreventRebootRequired=false In most cases, the issue has been resolved either by reinstalling a previous version of Thunderbird or by updating to the immediately higher available version. Could you please help us identify what is causing this problem? Are we not using the correct method for deploying the updates? Thank you very much!
