How to disable Sending Message Prompt in Thunderbird email client (2022)?
If you are using Thunderbird, you might have noticed that when “Send” button is pressed, Thunderbird by default shows a “Sending Message” progress prompt when attempting to send the email. Depending on network conditions, it may disappear quickly or it will be there for some good 20-30 seconds and you can’t go back and do something on Thunderbird. This can be a bit annoying at times.

So we’ll see how to disable this prompt in Thunderbird email client when sending emails.
This is what it looks like when the SEND button is clicked.
To disable Sending Message Prompt in Thunderbird email client, follow the steps below.
- Open Thunderbird > Click on TOOLS > Click OPTIONS
- In the search box, type “EDITOR”
- Click on “CONFIG EDITOR”
Click on “I ACCEPT THE RISK”.
In the next window, you will see a list of settings.
Type “SendInBackground” in the search box.
The default value is FALSE for “mailnews.sendInBackground”
To change it to TRUE, double click on the row showing “mailnews.sendInBackground;false”. The value will change to TRUE.
