I noticed that when I am writing in Firefox that that the word labled comes up as incorrect - with a red line under it (even though it is spelled correctly - in English [UK]) - and does not have a correction - if it is wrong (but it isn't). Why is this?

If only I could make British English the default and have it stick. It always reverts to American English.
