Change the default sorting order in Thunderbird

Question

Thunderbird (2.something here as 3 is still not stable and had some nasty bugs last I tried) sorts mails by date by default. This is fine, however, it sorts them so that the newest ones are at the bottom of the list, which ... is not fine. Since Thunderbird saves its sort settings on a per-folder basis (and I have many folders) I regularly run into folders I've rarely or never been in which still have the old sorting order.

Is there any way to globally change the default sorting order to "Threads, newest messages at the top" (or anything else, which, I assume might be possible as well then)?

Answer 1

Tools > Options > Advanced > General > Config Editor

Type "mailnews.default" in the Filter bar to bring up four (4) preferences to configure. It will display similar to below:

Preference Name                      Status       Type        Value
mailnews.default_news_sort_order:    default      integer     x
mailnews.default_news_sort_type:     default      integer     y
mailnews.default_sort_order:         default      integer     x
mailnews.default_sort_type:          default      integer     y

In the above, replace the x and y of the value by double-clicking the name of the preference and replacing it with one of the following values as required:

x (see https://developer.mozilla.org/en/nsMsgViewSortOrder)

1 = Ascending
2 = Descending

y (see https://developer.mozilla.org/en/nsMsgViewSortType)

17 = None
18 = Date
19 = Subject
20 = Author
21 = ID (Order Received)
22 = Thread
23 = Priority
24 = Status
25 = Size
26 = Flagged
27 = Unread
28 = Recipient
29 = Location
30 = Label
31 = Junk Status
32 = Attachments
33 = Account
34 = Custom
35 = Received

So if you wanted to sort all mail by Thread, Descending (newest at top), the preferences in the config editor will look like this:

mailnews.default_sort_order:    default     integer      2
mailnews.default_sort_type:     default     integer     22

Answer 2

Using about:config (under Preferences -> Advanced -> General)

mailnews.default_news_sort_order: news sort order
mailnews.default_news_sort_type: news sort column
mailnews.default_sort_order: mail sort order
mailnews.default_sort_type: mail sort column

had this saved in a text file, got it from an article a long time ago don't remember where, but those are the values that will flip sort order.

Answer 3

A simpler solution : Using the Thunderbird SortPref module.

Provides settings to control which order messages are sorted initially and by which field as well as whether to display in threaded mode. Please note this data ends up stored in each folder, so changing control values only affect new folders or those with a rebuilt index. The mechanics are described in https://bugzilla.mozilla.org/show_bug.cgi?id=86845 - this extension merely adds gloss to somebody else's actual code.
