リリースノートに以下のように書いてあるね。
For Windows Vista users, Thunderbird 3 Beta 1 is now integrated with Vista search results.
On first start, Thunderbird will prompt to install its indexing system into Windows Vista and you can choose to see Thunderbird email and news messages in Windows search results.
これで納得・・・。
