Search in all mailboxes and accounts in Thunderbird

Question

How can I search for a sender or string or whatever in ALL mailboxes in Thunderbird?

I use about 10 accounts and it is horrible to search every account separately.

Are there plugins for this?

I am using Thunderbird (in fact it is Debian 5, Icedove 2.0.0.24)

As far as I can tell there's no extension to do that... The closest you could get would be to enable message archiving, set everything to archive to a single location, and then search that location.
