Mozilla ThunderBird setting to place reply text on top of email thread content

The default ThunderBird settings appends your reply to the end of the thread. To change this to put your reply contents Before the other content of the thread, please do the following:

1. Go to ThunderBird -> Tools Menu -> Options


2. Go to Advanced -> General -> Config Editor


3. In the warning box, click "I'l be careful, I promise" and really, be careful with the next steps


4. In the filter box, type reply


5. Look for the row with Preference name "mail.identitiy.default.reply_on_top". Change its value from 0 (default) to 1.

I always wonder why Mozilla does not keep it to 1 by default, though?
