I had similar issue and discovered that they had changed the preference name. Previously each part used: ondate separator authorwrote colon requiring these prefernces: mailnews.reply_header_authorwrote

   Default: %s wrote
   Thunderbird replaces the %s with the author's name or e-mail address. 

mailnews.reply_header_colon

   Default: : (colon)

mailnews.reply_header_separator

   Default: , (comma space) 

mailnews.reply_header_ondate

   Default: On %s
   Thunderbird replaced the %s with the date and time. 

However, this has changed and the reference page has not been updated as yet although I have informed the powers that be.

Use these instead: If you have this setting: mailnews.reply_header_type; Value = 2

then it is using: mailnews.reply_header_ondateauthorwrote; Value = On #2 #3, #1 wrote: where #1, #2, #3 refer to name, date, time in that order.

so I would see: On Sun 16/09/14 08:38PM, Persons name wrote:

All the info is now in one line so not requiing individual settings.

If you need to create the preference:

Tools > Options > advanced > general tab clickon 'config editor ' button

right click in a blank space and select: New > String

Tried to do that but, nah, prefs.js does not get read by FF. Thanks for your help ...

Tried to do that but, nah, prefs.js does not get read by FF. I'm not really up to speed with doing this. I think I got lucky when I did the last/first "wording", but TB seem to be missing something.

Ahhh... prefs.js is the Mozilla equivalent to Windows registry. Firefox and Thunderbird both have such a file for storing your preferences. It shares a file extension with JavaScript, so double clicking on the file will try and run the program it contains, if nowhere else in a browser window. I assume that is how your managing to get Firefox into your little peccadillo.

Edit the preferences in the config editor, if your not already. Then restart Thunderbird to make sure the update is Read. Many config editor preferences are only read on application launch, so a restart is just good practice even if not required.

Note that when Thunderbird closes it updates the prefs.js file. Using the config editor causes no issue, but if you forget to close Thunderbird while you edit it in say notepad natively and later close Thunderbird the prefs.js you saved will be overwritten. Hence my recommendation to use the config editor. It is a little pokey, but a surer result is the outcome and a total corruption is far less probable as you can only edit one preference at a time.

Hi, This is what I want to say ... On this wonderful day, 4/09/2014 10:21 p.m., The esteemed Trade Me expounded mellifluously, eloquently and with the utmost intelligence:

and this is what I have. (happy to edit the js file as this was how i did it originally).

user_pref("mailnews.database.global.datastore.id", "266c5669-a317-41f7-a608-6b66febbd82"); user_pref("mailnews.display.html_sanitizer.allowed_tags.migrated", true); user_pref("mailnews.downloadToTempFile", false); user_pref("mailnews.emptyTrash.dontAskAgain", true); user_pref("mailnews.force_charset_override", true); user_pref("mailnews.html_domains", "netscape.net,netscape.com,aol.com,cs.com,yahoo.com,hotmail.com,msn.com"); user_pref("mailnews.playback_offline", false); user_pref("mailnews.quotingPrefs.version", 1); user_pref("mailnews.reply_header_author wrote", "The esteemed %s expounded mellifluously, eloquently and with the utmost intelligence"); user_pref("mailnews.reply_header_ondate", "On this wonderful day, %s,"); user_pref("mailnews.reply_header_separator", " "); user_pref("mailnews.reply_in_default_charset", true);

Do not edit prefs.js, use the config editor as I advised and enter the info as advised.

In thunderbird: Tools > Options > Advanced > General tab or Menu icon > Options > Options > Advanced > General tab click on 'config editor ' button it will tell you to be careful :)

In top search type: authorwrote

If you see this line: mailnews.reply_header_ondateauthorwrote; Then right click on that line and choose 'Modify' Then type: On this wonderful day #2 #3 The esteemed #1 expounded mellifluously, eloquently and with the utmost intelligence

If you do not see that line: right click in a blank space and select: New > String It will ask for a preference name: type: mailnews.reply_header_ondateauthorwrote click on OK then it will ask for the string: type: On this wonderful day #2 #3 The esteemed #1 expounded mellifluously, eloquently and with the utmost intelligence

click on OK to create the preference. close the about:config window - top right X Click on OK to save Options changes.

You may need to close and then restart Thunderbird.

You, my friend are a legend. All up and running perfectly. Thank you so much. Regards Guy.
