Quick Tip: Spell Check Firefox Text Input Fields

We’ve all seen misspelled article titles (especially on Doesn’t Firefox have built-in spell checking?

The reason why article titles and search terms aren’t included in the spell checker is because Firefox only enables the spell checking on textarea fields, not text input fields. Lucky there’s a quick fix for this.

To change this setting, just type about:config into the Firefox address bar, and then filter by this:



Just double-click on the item in the list and change the value to 2, as shown. No restart needed.


No more typos in search terms!

    I like your tip, it is very easy for me to understand. Great site! Love, Mom

    Wow, nice one. I always wondered about that. Thanks.

    Hey thanks for that… been putting off upgrading to 2 because I’d noticed that the spellcheck only covered the textarea on another computer, and my extension checked em all…

    But I bit the bullet and did it, so you just saved me from ripping out my hair. :)

    I found that using this option can lag the browser on some computers if there are a lot of textfields on one page; although, I haven’t tested it in a while, so it is possible it has changed since then.

    Hmm, I just did that and it was already set to 2. and it doesn’t spellcheck. Well, it does down here, but not up in the toolbar . . . PC, Windows 2000, whatever the latest firefox on their site is (wiped my computer a couple days ago (ouch) but techie hubby tried lots o stuff first, over a period of time).

  6. What is Firefox?

    You can also simply right-click text fields that you want to check and select “spell check this field”.

    Does it do this by itself in Firefox 3?

    Awesome Tip. Thanks for sharing. I was getting tired of right-clicking to spell check input fields.

    Thanks a lot. I did not know about that “about:config” you can type in firefox address bar. But i am glad i know now. I taught i have to write out some code by myself to enable automatic spell check in input fields, but it’s solved now.

    Thanks again!

    This is a very useful tip – I always enable it on any Firefox I use!

    Yes – but in version 3.6 this made no difference in the UK – reason was you need to add a GB English dictionary – then hey presto – it works fine
