I noticed on my notebook this morning that SpellBound was still functioning with Ff 3. Turns out my desktop only had v2. I prefer checking/correcting after finishing a message. Ff still underlines everything as you type. Get it here. Use the modded version, save it to your desktop and when ask what to open with choose Ff and it will install like any extension.

I thought I was the only one that found Firefox's built in spell check annoying. I don't like check spelling as I type spell checks either. I prefer to finish what I want to type than check the whole thing at once. I use The Google Tool Bar for this.

I hate tool bars, although I'm sure they are very useful.

I use it for more than the spell check. It's the only tool bar I have or will install.
