Check the Spelling of Every Message Automatically in Mozilla Thunderbird
To have Mozilla Thunderbird check the spelling of every message automatically right before it is sent:
- Select Tools | Options…, Thunderbird | Preferences… or Edit | Preferences… from the menu.
- Go to the Composition category.
- Choose the Spelling tab.
- Make sure Check spelling before sending is checked.
- Close the preferences window.
From now on, Mozilla Thunderbird will run the spell checker against every message before delivering it, and maybe deliver some spelling corrections, but certainly lots of giggles.
