Review for StartupMaster by SciFiBob
Rated 5 out of 5 stars
This month (March 2011), I started to get a master password login prompt for each account in Thunderbird.
But no more. Installing the latest version of the extension in Thunderbird solved my problem.
Btw. I had this extension installed in Firefox for a long time, and it has been working flawlessly (if that's a word..).
