Enable Automatic Spell Checker in Firfox : Trick

If you are a Firfox user, you must have noticed that its in-line Spell Checker doesn't work in forms, text boxes, rich text editors, etc. You need to manually right-click in the box and enable "Spell check this field" option to check the spelling.

Here is a solution for this annoying problem:

1. Type about:config in Firefox addressbar and press Enter.

2. Now type layout.spell in Filter box.

3. You'll see layout.spellcheckDefault in result.

4. Double-click on it and change its value to 2

5. Thats it. Now Firefox will check for correct spellings in every textbox, etc in webpages.
