How to enable Spell Check on Firefox?

December 2016



The Mozilla Firefox offers you this option… Sometimes you can do mistakes by typing so now we will see how to activate this option:


• On your Mozilla Firefox Browser open a new tab (CTRL+T).
• On the Address Bar type: about:config
• A message will appear “This Might void your warranty’’.
• Click on “I’ll be careful, I promise!’’

• A list will then appear, using the ‘’Filter’’ bar type: ‘’layout.spellcheckDefault’’.
• Double click on layout.spellcheckDefault in the list.

• Change the value to ‘’2’’ then press ‘’OK’’.
• So now when you are typing a word, firefox will check if any mistake is done.

When you are typing a word or a text, it will be underlined in red, right click and select the right word or text.
