And when I type sulphur my Mozilla Thunderbird spell check offers
sulfur! I knew it had changed sometime over the last fifty or sixty

And the dictionary:
*usage* The spelling /sulfur/ predominates in United States
technical usage, while both /sulfur/ and /sulphur/ are common in
general usage. British usage tends to favor /sulphur/ for all
applications. The same pattern is seen in most of the words derived
from /sulfur.
