I've set up a Smoketest test run for Thunderbird 3.0b2 in litmus . It's
available at <https://litmus.mozilla.org/run_tests.cgi?test_run_id=39>.
If you find any bugs while running those tests please make sure to make
bug 477222 depend from your bug. The build to test against can be found
and there is already one bug reported against it, 479206 which is a crash.
http://wiki.mozilla.org/Thunderbird:Testing lists additional ways to
contribute to Thunderbird's progress. We also have a mailing list where
those things are announced :
