I really like this app, but for some reason when I try to translate Russian to English it tells me its waiting on server response or that I'm a guest user and current period quota is used up and it no longer works for me the majority of the time. Please Developer of this extension SEE THIS REVIEW and please fix it. Your app has helped me so much in learning Russian and now I no longer can use it =( I used this extension for so long and to no longer be able to use it sucks, because there is nothing out there like it.
