Rated 5 out of 5 stars

Doesn't work with Firefox 9.0.1 or Thunderbird 9.0.

- I reinstalled on both. I wonder if using other spellcheckers make a difference to this? I use U.S. and British English on the side, and in the new TB, I had to reinstall British English.

- This is a favourite of mine, so it would be nice to have it geared for the new one. Or if I knew what makes it not work, I'd volunteer to fix it.

- Firefox/T-bird have gone through a rapid-fire major version iterations, I know.

This review is for a previous version of the add-on (2.0.1-signed).
