Is there a spellcheck for FireFox browser?

[macko]

So I'm on a Mac running Safari, which seems to work okay until I want to log into my work email address, blah, blah, blah. I gave FireFox a try and I like it ... except it doesn't have a built-in spelling check like Safari.

Is there some kind of an extension I can get or is that just something I have to live with?
