Works as a bookmarklet. Just hit the SpellingCow bookmark button & it checks the spelling in any form field. Ad supported.

FF 2 does that without any fiddling about.  Keep up!

I am surprised the google toolbar hasnt added this or maybe they have?

Er, yes, there's a "Check spelling" button in the Google toolbar.  What are you people, blind?

There's this firefox extension called "spellbound"...

Extension? Upgrade Firefox? This is just "drag this link onto your bookmark bar."

Thats the way all firefox extensions should be installed: drag a link to your bookmarks.

The integrated solutions are MUCH nicer, though.  FF2 gives you neat little red underlines as you type and that you can right click on to get suggestions, just like Word.
