How to re enable confirmation warnings before deleting an email or Emptying the Trash Folder on Mozilla Thunderbird
I tend to delete emails from Thunderbird using SHIFT+DEL out of habit when I’m sure I don’t want that message any more, but recently I accidentally ticked the check-box that tells Thunderbird not to ask me if I’m sure I want to delete such message(s).
Although safer, I didn’t want to delete messages then empty the trash. For whatever reason I wanted to return to the past behavior. In case this has happened to you, here are the steps to get the warning back:
- Go to the Tools Menu
- Click on Options
- Click on Advanced
The picture below shows the Options-Advanced Window. In the lower right you’ll see the “Config Editor” button. Click on It.
You will receive a fair warning as this. Click on I’ll be careful, I promise!
Now you’re on the configuration section. The value I want to change here is:
mail.warn_on_shift_delete from false to true. To change the value, just double click on the line.
If you want to re-enable the confirmation for emptying the Trash folder, the value you should modify is:
mailnews.emptyTrash.dontAskAgain from true to false.
