Firefox related problem and question

[Sazelyt]

Before, when I was typing, firefox was able to show me the spelling mistakes (at that time, maybe the text field was not light-yellow colored).

Although I haven't updated firefox, or changed any related setting, now I can't do it. (I can try google's spell-check, but firefox's was automatic and easier)

Is there any change related to the forum settings that disabled this?

You have most likely switched (somehow) to the WYSIWYG editor. :)
No SpellCheck there...

Cats is correct. You are using the "WYSIWYG (http://en.wikipedia.org/wiki/WYSIWYG)" editor.
Why, if you didn't select the option, I don't know... possibly another forum problem. ::sigh::

Ok, the problem was solved, thanks. As you guessed correctly, the WYSIWYG option was on, although I don't remember if I selected the option or not, possibly.
