It would be nice if they'd just fix the spell checker in Thunderbird
It would be nice if Mozilla would just fix the spell checker in Thunderbird. It has to be the absolutely worst spell checker on the planet when it comes to the English language. Misspell a simple word like "reservoir" to, say, "reseviour", and it's guesses are: previous, previously, deviousness, Saviour's, deviously, devious, deviousnesses, deviousness's, and Saviour.
And this is typical of its behavior.
