To diagnose problems with Thunderbird, try the following:

• Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.

Hi Matt,

I've tried to restart Thunderbird with add-ons disabled but the issue remains. The reply stays below the text and I can't understand why.

Assuming you have done this:

• closed any open 'Write' windows.
• right click on mail account in Folder Pane and select 'settings'
• select 'Composition & addressing' for account
• select 'automatically quote the original message when replying'
• select 'start my reply above the quote'
• click on 'OK'

Try checking this:

• 'Menu icon' > 'Options' > 'Options' > 'Advanced' > 'General' tab
• click on 'Config Editor' button

it will say be careful :)

In top search type: on_top This will list the various accounts / identities where you have selected to 'reply_on_top' and the Value should say 1 eg: mail.identity.id1.reply_on_top; Value = 1 Those will be shown in bold text. If it is not saying 1:

• right click on line and select 'Modify' to get a box allowing to change the value.

If you already see all seems correct then check this line:

• mail.identity.default.reply_on_top

If the value is 0 then modify to say 1

• Close window using top right X
• click on OK

Exit and restart thunderbird. Select email and see if 'Reply now works.

This fixed the issue, thank you!
