Firefox's spelling correction is very poor. For instance, try spelling the name of a country starting with a lowercase letter and omitting a single letter. "argetina" suggests "retina", Argentina isn't in the list. "nethrlands" suggests "fatherland", Netherlands isn't in the list. "ukriane" suggests "hurricane", Ukraine isn't in the list. It fails for every country I try.
