TestComplete 9.36 doesn't recognize objects in Thunderbird Extension Management Tab.

Hello,

Objects in Thunderbird Management Extensions Tab are not detected by TestComplete. I use Thunderbird version 31 and I did the following actions:

1. In Current Project Properties -> OpenApplications -> MSAA: Add a new category named Mozilla* to access Thunderbird objects.
2. Launch Thunderbird: Main window contains a tab displaying the current account.
3. In Thunderbird select Tools -> Extensions. A new tab is opened in the main window.
4. Display Object Spy in TestComplete.
5. Drag the object spy target on the Thunderbird Extension Tab: it highlights the frames from the objects in the current account tab (which is hidden).

Is there anything to do to browse those objects?
