I love the idea of local machine learning translation instead of everything going through creepy Google. Been using it for a while now and it's actually working really well. However, I wish it would have an auto-detection of language on the page and ability to select your preferred language that you want to translate into and just have it automatically translate everything automatically. I'd also like to have website translation to be automatic as I browse without having to always manually click button to automatically translate things as I browse. Having said that, if these controls can be adjusted in extension settings, there is no need to have the toolbar always visible. One could have it enabled if desired, but we already have quick access button for extension itself in the URL bar if you need to change that. If this stuff can be addressed I'm giving it 5 stars easily. Thanks Mozilla, really cool extension.
