Thunderbird 24 beta is out. This is the first beta of the next Major release of Thunderbird - with many, many core improvements and many small bug fixes (we are missing locales on windows). Good news is Lightning was build at the same time , so calendar users we’ll be able to download their favorite extension.
Starting now we are running a Test week , in order to catch any major regression that didn’t get caught. There’s tow ways to achieve this and both are difficult.
1) We need a few more tens of thousands of users (so Thunderbird get’s tested with AVs, Anti-spam solutions etc …) so raise our low rate of 0.43% of beta users compared to mainstream users. People tend to be afraid of running betas for email while not for things like a web browser. I had the same thinking before testing Thunderbird became my main Activity. Since February 2009 - I’ve been using various betas/alphas and nightlights of Thunderbird, and didn’t loose a single email on either imap nor pop. Your mileage may vary but It’s been pretty stable for me.
2) We need people with more desktops setting to helps us during our first test week - which is starting today. That’s easier than 1 as you can just use a test account with no “important” emails in it. Then you’ll need to run the beta on that account and spend sometime testing ( that means reading a test - trying to do it in Thunderbird and report if it worked or not). This is less stressful about the mails you care. All you need is some time, the capacity to read English , and try things in Thunderbird. The tests are at https://moztrap.mozilla.org/runtests/environment/1974/ , and the quality team is available on irc.mozilla.org on #tb-qa (just click that link to talk to us). Bugs found need to be reported in bugzilla and marked blocking of https://bugzilla.mozilla.org/show_bug.cgi?id=870347 (if that’s chinese to you just add :usul on the cc list).
3) if you don’t have time this coming week - consider joigning our other efforts outlined at https://wiki.mozilla.org/Thunderbird:Testing
