Calendar Community Testday On Thursday, December 04

The next test day will be held on Thursday, December 4th. This time we want to take a look at Sunbird and Lightning 1.0pre builds in Thunderbird 3.0b1pre. Please keep in mind both are alpha versions! Therefore you should take following steps:

  • Though we do not expect things to go wrong, we always strongly encourage you to back up your profile, and to do your testing on a “test” profile.
  • Backing up a profile is easy:
    1. Find your profile directory: Windows: %AppData%Thunderbird, Linux: ~/.thunderbird, MacOSX: ~/Library/Thunderbird
    2. Copy the root of it somewhere else, for example copy the Thunderbird directory and everything below it.
  • Creating a testing profile is also easy:
    1. Launch your application with a ‘-P’ option from a terminal prompt.
    2. Create a new profile by clicking the ‘Create Profile’ button.
    3. Click ‘Next’, Give it a name like “Testing Profile”, click ‘Finish’.
    4. Select the testing profile, and click the ‘Start Shredder’ button.
  • Remember that you will have to start the application with the -P option during testing so you can pick your testing profile.
  • Once you have finished testing, you can delete the extra profiles, and you will be back to normal. If something goes terribly wrong (although we do not expect it to), close the application, and just replace the profile with the backed up copy. That will reset the application to the way it was before you started testing.

The goal of our test day is to run as many Litmus test cases for Sunbird and Lightning as possible. If you find outdated or broken test cases, please leave a comment.

There are also some fixed tb-integration bugs that need to be verified. You simply have to add a comment to the bug report stating what version and operating system you used while verifying the bug fixed.

Join us in the #calendar-qa IRC channel on Thursday. All the information on the testday is on our usual Test Day wiki page.

Hope to see you in #calendar-qa!



  1. Can you please point out the most probable location for the profile data on a Vista 64-bit installation? I´m trying to install Sunbird but I need to completely uninstall the previous one, since it won´t start otherwise.

  2. Can please point out which versions of
    – Thunderbird 3
    – Lightning 1.0 pre
    are going to be tested, as I get error messages trying to install Lightning under TB 3b1. Download links are very much appreciated.

  3. Hi big_surfer,
    If you do not get any response from the mozila team download the latest nightly and modify the minversion and maxversion in the install.rdf file in the xpi installation file. I modified them to 3.0b1 (3.0b1 was the version of my thunderbird) and it worked.

  4. Hi aerosmith!
    Thanks for the hint, but my install.rdf yet shows 3.0b1 for min- and maxversion.

  5. “The latest Lightning builds have become incompatible with the Thunderbird 3Beta1 version that has recently been branched off. We will deliver a patch to make them compatible again. ”
    And none of the experts knew … ;-)
