WTF, why does my Firefox spell checker now think that "ti" is a word?¹ And so it doesn't put a red squiggle under it? I am a very good speller, but only a so-so typist; I know how to spell most words, but I make transposition typos pretty much every sentence. So I cast my eyes over the text entry field looking for red squiggles before I hit "Post". How do I take a word *out* of Firefox's dictionary? Argh. 1. Oh, it thinks re , mi, fa, etc. are too. Crap.
