I use both English and Korean for typing. Lately, when I type something in English while using firefox, it sometimes changes what I've written down into Korean. It happens when the word means something in Korean if I write it in korean keyboard, for example if I type 'skdleks' and press space bar, it automatically changes it into '나이단'. I want to shut it down. And I want to shut down the autocomplete too, but I can't find the way to shut it down. I love using firefox, but I feel bad when it happens. Thank you.
