Thank you very much for your software, it helps me a lot. I am not a native speaker and I haven't had practice in English for two years, but now I'm trying to recover my English.
I write in several languages (in Ukrainian, Russian, Spanish, Esperanto and English), and I prefer to write in English with British spelling. But when I enable the option of language auto-detection I have a problem: LanguageTool is sure that I'm writing in English (US) and show that words like "colour" or "organisation" are mistakes.
I think, it would be perfect to have the language auto-detection, but I want to see in my computer British English as auto-detected. How can I configure the LanguageTool Firefox extension for this?
