I like your work very much. In the past I was using another tool but it is not supported any longer (Babylon). I moved to ImTranslator and it works great, the comparison tool as well. According to my historical experiences I would like to know: will you get ready for Firefox 57+. When do you plan to be ready? Thx for any information.
ImTranslator version compatible for FF 57+ is under development, and will be available soon. In the meantime, you can try our Translation Comparison multiprocess extension : https://addons.mozilla.org/en-US/firefox/addon/translation-comparison/
