Since I have started this blog I have been scouring the internet looking for an acceptable spell checker for WordPress. To date I haven't found one that wasn't either a pain to install, use, or that I tried for a week and then found completely unusable. I really didn't think that highlighting my incorrectly spelled words could be that difficult in the day-and-age of AJAX.
Today I installed Firefox 2 and... *problem solved*. Firefox 2 includes a wonderful automatic spell checker that, like Microsoft Word, checks your spelling as you type and underlines any words that it deems misspelled. Just... perfect. Exactly what I was looking for.
There are a lot of usability fixes to FF 2 as well, making the UI that much more rock solid.
