BirdieSync add-on doesn't load properly

If BirdieSync toolbar doesn't display in Thunderbird or no connection is automatically made to BirdieSync server, it is necessary to check the status of BirdieSync add-on in Thunderbird/Sunbird:

Open Thunderbird/Sunbird menu "Add-ons/Add-ons" or "Tools/Add-ons" and select "Extensions" tab.
Check if BirdieSync add-on is marked as compatible and enabled.

If BirdieSync add-on is disabled, enable it and restart Thunderbird/Sunbird.

If BirdieSync add-on is marked as not compatible with current version of Thunderbird/Sunbird, follow the procedure described in this FAQ entry.

If BirdieSync add-on is supposed to be compatible with the version of Thunderbird/Sunbird but doesn't load properly, there might be a problem with Thunderbird/Sunbird extension manager cache. This problem can prevent BirdieSync sub-menu to be properly displayed in Tools menu or display an old incorrect version number in Thunderbird/Sunbird add-on list. More rarely, it can also make Thunderbird/Sunbird crash.

To solve this problem, it is necessary to remove BirdieSync add-on from Thunderbird:

  • Close Thunderbird/Sunbird
  • Uninstall BirdieSync, keeping BirdieSync user data (the checkbox must remain ticked)
  • Start Thunderbird/Sunbird to force BirdieSync add-on uninstallation. This step is important, do not miss it.
  • Reinstall BirdieSync
  • Start Thunderbird/Sunbird and check BirdieSync add-on state with Thunderbird/Sunbird menu "Tools/Add-ons" or "Add-ons/Add-ons"

In recent version of Thunderbird you may have to restart Thunderbird once more, so that BirdieSync add-on is properly loaded.

As an alternative, you may try to remove some files holding add-on informations in Thunderbird profiles:
