Robert Coleman has bravely made a commitment to compile and host the latest builds of Thunderbird with the patch applied that integrates with Address Book.
Many people hope that Thunderbird will one day support Address Book access, but although an Address Book patch 
has been created, movement on improving it or building into official Thunderbird builds has been slow.
In an email, Robert writes that he is now “hosting more up to date (ideally weekly) Universal Binary builds of trunk Thunderbird with the Address Book patch applied”.
The latest build on his site (3.0a1) was compiled on 6 December.
He also includes on his web page instructions and screenshots (and warnings and caveats) for adding the required preferences to Thunderbird’s pref.js file.
He warns that access to Address Book is currently read-only, that the code is a little unstable and that the build is not an official Mozilla one, so is not packaged with the usual Thunderbird branding.
Apple has released a security update that patches the recently discovered vulnerabilities in Mail.app, Safari and elsewhere.
