The Debian package mozilla-thunderbird 0.7.1-1, that is in the official repository as of today (see date of post), is unable to recognize your old profiles. If you are upgrading from an older version of Mozilla Thunderbird you will most likely be greeted by a “New account” dialog when starting up Thunderbird after the upgrade for the first time.
- In case you DID NOT UPGRADE already: The Debian maintainer has already provided a fixed version of the package, that somehow did not make it into the official Debian repository, yet. You can get the fixed package via apt-get from the unofficial Debian repository at
mentors.debian.netor you download the package from the Debian Thunderbird Home and install it manually viadpkg -i. - In case you DID UPGRADE already: You need to restore your old profile. This is done faster than it sounds. Just follow the instructions of Graham Smith from his original bug report. It turns out you just need to copy one directory and then edit a single file. This worked for me, too!
Shameless plug: If this post was useful to you, please consider buying yourself something from one of my Amazon stores: US store, UK store, FR store, DE store, CA store. If you're not into Amazon, why not donate something to GNOME, Mozilla or Wikipedia? Thank you!
