Customizing Thunderbird- Tweaks for mail client

1. Reply on top of previous message

One problem was that in Thunderbird, when you reply to a message, the new message was appended to the end of the message you were replying to. I was used to Outlook, so I changed it to behave like Outlook (and Thunderbird on windows). To add the reply on top, you need to do the following:

1. Goto Edit -> Preferences
2. Click on the 'Advanced' tab
3. Click on 'Config Editor...'

Now you would see the config editor.
In the top search box, type the following:

mail.identity.default.reply_on_top

If the value is set to '0', change it to '1' and the replies would start appearing on top.

2. Allow Javascript in Mails

Goto the Config editor as described earlier
Search for

javascript.allow.mailnews

Set the boolean to 'true' (Toggle)

3. Display last name first

Goto the Config editor as described earlier
Search for

mail.addr_book.displayName.lastnamefirst

Set the boolean to 'true' (Toggle)
Then search for

mail.addr_book.lastnamefirst

Set the integer to '1'

4. Add all incoming Email Addresses to your Address Book

Goto the Config editor as described earlier
Search for

mail.collect_email_address_incoming

Set the boolean to 'true' (Toggle)

5. Add default CC

Goto the Config editor as described earlier
Search for

mail.default_cc

Set the string to the required emailid

6. Not show send Progress

Goto the Config editor as described earlier
Search for

mailnews.show_send_progress

Set the boolean to 'true'(Toggle)

7. Check for newer version of Thunderbird once every week.

Goto the Config editor as described earlier
Search for

app.update.interval

Set integer to '604800'
(the number of seconds in a week)

8. Use threads like Gmail

Goto the Config editor as described earlier
Search for

mailnews.thread_pane_column_unthreads

Set the boolean to 'false' (Toggle)

PS.If you have heard : Mozilla might make Thunderbird a separate entity
