If you’re a web developer, you know that spell checking is a must-have feature in your browser. But what if you don’t have a spell checker installed on your Firefox? There are plenty of ways to get it up and running without having to install anything. Here’s one way:

  1. Open Firefox and type “about:config” into the address bar.
  2. In the “configuration” section, click on the “spellcheck” tab.
  3. In the “settings” section, set the following values to their desired values: “enable”: true, “spellchecker”: false, “language”: en_US.UTF-8, “browsername”: “firefox”,

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!
