Thunderbird 102


(Not tracked)

Steps to reproduce:

I volunteer on SUMO and we receive numerous complaints from those upgrading to 102, stating that addressbooks are empty after upgrade.

Actual results:

Addressbook found empty after upgrade.

Expected results:

Addressbook should have remained as before.

Thanks David. That's not good at all!

Can you please link some sample reports here?

Severity: -- → S2

Summary: 102 upgrade is destroying addressbooks → 102 upgrade is destroying addressbooks (often reported in support)

My error for not logging them all. Here is one: There have been so many problems, with lost accounts, lost messages, lost addressbooks, and many seeking to downgrade to 91 or quitting Thunderbird. I will work to capture more as I see them.

Flags: needinfo?(dskirk) - Not many details.
Note that and were reported in 2020 and 2021 for earlier versions. Too bad no one helped the guy who lost 800 customer addresses back in 2020 :-(

I don't know if this is related or not. The addressbook is there after upgrade, but search can't find anything.

When the 2020 and 2021 items were reported I think some issues were still being investigated (and fixed). So IMO there's a fair chance they were since resolved.

As for the current reports, address book migration is quite old, so I'd suspect these may not be related to the past ones, and I'd worry some new issue has emerged in version 102. But with roughly 500k users on version 102 and only a few issues reported, if there is in fact an issue, I doubt we are facing a problem of huge proportions. I've posted a response in those support topics.
