I'm not sure if this a Firefox issue or an IPB issue, but the nifty new Firefox spell checker doesn't work when rich text editor mode is enabled. I've been using the RTE on here lately, because the font size more closely enables what a post will look like once I have posted it. That's a great new feature, but the spell checker is preferable.

Anyway, it's possible that this is a Firefox issue, or an issue with the way that rich text editors work, but I thought I should point it out.

its not an IPB Issue because it dosen't work on vbulletin's rich text editor.

Why not type your post in the standard editor and then once down switch it to rich text?

I know its not a fix but is a workaround.
