Typos, like mistakes, are natural. As fingers hurry over a keyboard, they sometimes hurry too fast and too far. Other times, it's simply a matter of not knowing how to spell a word.

Whatever the case, you can use Mozilla Thunderbird's spellchecker to catch—and correct—typos and spelling errors. With inline spell checking, you can even correct your errors immediately as you type.

Check Your Spelling as You Type in Mozilla Thunderbird

To have Mozilla Thunderbird check the spelling in emails as you write them:

  1. Select Options from the Tools menu in Mozilla Thunderbird, located at the bottom of the Tools dropdown menu.

  2. Select Composition tab.

  3. Choose the Spelling tab.

  4. Make sure Enable Spell Check as You Type is checked.

  5. Select OK to close the Options window.

While composing an email, you can turn the inline spellchecker on or off by selecting Options > Spell As You Type from the menu.

Choose Your Language

You also can specify the language Thunderbird uses for spellchecking under Tools > Options > Composition > Spelling.
