Comment 59 for bug 940631

Currently running 60.4.0 on Linux

The problem persists and gets worse with every account that is added. Currently, I get 6 prompts when starting TB.
6 is the exact number of authentications it needs to perform:

3 IMAP accounts
1 CalDav calendar
2 CarDav address books

As before, only one actually needs to be filled in correctly, the others can be cancelled.
None of the accounts uses OAuth.

I think that without the StartupMaster extension I would not be using TB anymore.
