Early on, I installed a Firefox spell check plugin into WordPress, and didn't have any problems - but somewhere along the way, something broke. Right now, when I'm in the WYSIWYG editor view, incorrectly spelled words are not underlined red (Firefox 3.0.3). I know my Firefox spell checker is working because on other sites, including this one, I see my incorrectly spelled words underlined red.
What's odd is that words that are hyperlinked are spell-checked - and I can toggle over to the HTML view and see my incorrect words underlined red. But in the regular view, I have zero spell checking.
Any idea what's going on here? I have the same problem on two computers, both with Firefox 3.0.3, so I don't think it's a problem with my particular install of Firefox.
