Does not recognise the web language. Cuts the sentence and translate only a part. If your "translate to" language is other then English, to find a right language in the pop up Translator window is a real task.
Sometimes does not pop up on certain text.
I downloaded this 12/26/2016 on El Crapitan 10.11.6 but get:
"Safari can’t install this extension"
An error occurred while installing the extension “Translate”.
I prefer the Franker (https://code.google.com/p/franker/) Safari extension. It's unobtrusive, I have it set up so it appears only in the contextual menu, no toolbar icons. You can choose to translate entire pages or just selected text (for when you need just a little help with a language you're learning). It can be configured to use either Google Translate or Microsoft Translator, and it's free.
Does a great job with great options but has one glaring flaw. I want the option to remove the Toolbar Icon entirely and just use the Contextual Menu instead. I have too make icons up there already I don't want. Otherwise, great Safari Extension!
