Follow up from bug 1641581. The Firefox Nightly Address Sanitizer builds automatically update:

The builds are self-updating daily like regular nightly builds (like with regular builds, you can go to “Help” → “About Nightly” to force an update check or confirm that you run the latest version).

The Thunderbird Daily ASan builds provided in bug 1641581 do not auto update, so users have to manually download the latest artifacts from treeherder every day. Auto updating ASan builds would make them much easier to regularly use.

Depends on D143516

D143725 needs to land before this does

Thanks for the information. I downloaded one of the builds after this comment, but automatic updates do not seem to be working. As you can see from the screenshot, it says it is up date, but it is actually two versions old (today is 04-18).

Thanks for testing. I hadn't had a chance to verify the Windows build yet.

The update channel in your screenshot is wrong; it should say "nightly", not "default".

Until I get a chance to correct the build, you can modify defaults/pref/channel-prefs.js in the install directory and change app.update.channel to nightly. This file is not overwritten by an update so it should stick.

The Linux build is correct, it's not clear what got missed in the Windows build.

I checked today's Daily, and the update channel on the Windows build is set to "nightly" as it should be.

IIRC, that channel-prefs.js file will not get overwritten if you reinstall on top of one of the builds that had the update channel set to "default". You can edit it as I described above, or you can uninstall then reinstall.
