Hey, I'm testing a new spellcheck called After the Deadline. It's a new add-on for Firefox & Chrome.
So far it seems to offer better suggestions for misspelled words and it's also configurable for detecting various grammatical mistakes. It also works
for various languages.
Only thing I don't like so far is that it doesn't work in real-time. It looks like you have to manually click it to make it work.
