Anyway - I'm Brian, and I am a Mac User.

("Hi, Brian")

It's true, I do not use a PC at home (except the occasional VMWare virtual PC session). So while I'm happy fixing PCs and offering PC advice, I'll occasionally dole out some Mac love.

For the Mac folks out there, do yourself a favor and download Minefield. They're PowerPC or Intel optimized builds of Firefox 3. The performance of the Intel optimized build makes me never want to go back to Camino again. Blazing fast startup and page views. Truly awesome. (They're named "Minefield" so as not to interfere with any Mozilla/Firefox trademarks.)

In your Firefox address bar, type

about:config

This will open the Pandora's Box of Firefoxy goodness. (I say it's Pandora's box because much evil and sadness can come to an errant entry... but much good can come of it as well, so tread carefully and don't change anything you don't understand.)

From here, you can enter into the filter screen the following bit:

layout.spell

This will filter the gigantic list into one entry:

layout.spellcheckDefault

Double-click on the entry there and change the value to 2. That will turn on spell-checking in all Firefox input forms.

Missspellinngs be gone!
