First, thanks for introducing this feature [which is '''not''' the same as whole page translation]. It fills the gap created when, years ago, Mozilla disabled a translation plug-in. IMHO it's not ready for prime time, because: 1. When I highlight a word or phrase then r-click and Translate, this feature offers to translate From English, To English. Don't need software to do that. Even if, on same web page, I set source language to Italian, when I try to translate another section, the tool defaults to no-op same language. For many years other translation tools have been fairly good at detecting source language. Do I really have to download languages for ONline translation (as in "Set your language and site translation preferences and manage languages downloaded for offline translation.")? Anyway, without language detection the tool loses much of its value. 2. Even once you make the effort to set source language, the translation is often wrong, sometimes simply repeating the selection. So, nice idea, yes you say "Beta" but it feels more like "Alpha."
