Even so, when you’re filling in online forms, it can be useful to know that you’re not including a ton of spelling errors in your strongly worded message to customer services. Thankfully, Firefox comes with its own spell checker to point out any howlers before you hit submit. If you want to know how to keep the typos out of your online forms and social media posts, learn how to use the Firefox spell checker below.

What is the Firefox Spell Checker?

Firefox has a built-in spell checker that compares what you type when using the browser to its dictionaries. If it spots any words that it believes are spelled incorrectly, it will underline them. You then have the option of correcting the underlined word to one of Firefox’s suggestions. You can choose from a range of available dictionaries, and even add your own words to the dictionary, too. The spell checker is on by default, but it is only active in text boxes that contain more than a single line. Any typos you put in single-line text boxes won’t get picked up.
