Mozilla has been testing a Firefox 2 --> 3 major update to see if we need any fixes before Fx3 ships, and we noticed that 2.0.0.11 zh-TW has the en-US dictionary but 3.0b2 doesn't have any. This is probably fallout from switching from myspell to hunspell for the dictionary engine, which means the dictionary files need to live in l10n/$locale/extensions/spellcheck/hunspell rather than l10n/$locale/extensions/spellcheck/myspell If you're intending to restore the dictionary, then it would be great if you could get that before 3.0b3. If you can do that without changing the file names, then that would be much appreciated; but as long as you explicitly note it in this bug then it's not a big deal. If not, then we'll need to know, so we can explicitly remove the dictionary files on update and Windows pave-over install.

I think zh-TW has the en-US dictionary is much better, so how do i restore the dictionary?
