Config Editor
The Config Editor is accessed via Preferences > Prefernces > Advanced -> General > Config Preferences→Preferences→Advanced→General→Config Editor.
Default web browser
Thunderbird defaults to using the desktop's default web browser. To override this setting, use the config editor (below) to ensure network.protocol-handler.app.http and https exist with the path to the desired browser program. For example, for firefox ( this did not work on Ubuntu 12.04 Precise):

network.protocol-handler.app.https,
string,
/usr/bin/firefox
Gmail client
There's a Mozilla KB page on configuring Thunderbird as a Gmail client, listed in the Reference section below.
IMAP settings
Server Settings -> Advanced -> Show Only Subscribed Folders
In Config Editor (above):
- mail.imap.auto_unsubscribe_from_noselect_folders Default and desired value: true
- mail.server.default.check_all_folders_for_new Default false. Setting it true avoids the user having to wait for mails to be downloaded on opening folders other than the Inbox – but it may degrade overall performance, especially when Thunderbird is started. When the IMAP server is local it should be OK. In case of several IMAP servers, the setting can be made for specific servers using mail.server.server<n>.check_all_folders_for_new
Usage
Backup considerations
Thunderbird will rebuild .MSF files as needed if they are missing so no need to back them up.
If backups are incremental, big folders (documented below) can result in huge backup data volumes.
Folder maintenance
Big folders
Thunderbird uses a single file for some folders: Drafts, Inbox, Sent and Trash. When they grow large, say > 250 MB, it is prudent to reduce their size:
From kb.mozillazine (http://kb.mozillazine.org/Compacting_folders): If the folder is severely corrupted, deleting the .msf file won't help much, and compacting the folder may just make things worse because Thunderbird can't reliably figure out where a message ends anymore. You'll typically run into this only with the Inbox folder. It's much more vulnerable to corruption because it frequently has both lots of messages and a high percentage of deleted (but not visible) messages. That's why it's recommended that you move messages you want to keep to other folders/child folders rather than keep storing them in the Inbox."
Troubleshooting
Logging
Sample script to be run in the desktop environment (TODO: $LOGNAME does not have a value ...? The ; after imap:5 is spurious ... ?):
#!/bin/bash
export NSPR_LOG_MODULES=imap:5;
export NSPR_LOG_FILE=/tmp/$LOGNAME.imap.log
/usr/lib/thunderbird/thunderbird &
Subscribing
After IMAP changes (including a cyrus reconstruct that fixed something), right click the account and choose "Subscribe ...".

Subscribing
Depending on the setting of "Show Only Subscribed Folders", folders on the server that Thunderbird is not subscribed to are invisible or shown greyed out.
To subscribe to folders, right click any folder and choose Subscribe. Expand the list until the folders you want to subscribe are visible, toggle (\?) the checkbox and click Subscribe.
