Opera usually is more efficient with resources than Chrome...
There's no point Opera adding translator plugin/service.. as it would most likely use Google anyway, or Yandex etc.
Not to mention that such a plugin in Chrome is very dubious from privacy point of view - and most likely Google harvests the data for marketing purposes as they do read every mail in Gmail accounts.
Get this open source translator:
TransOver
https://chrome.google.com/webstore/detail/transover/aggiiclaiamajehmlfpkjmlbadmkledi
https://github.com/artemave/translate_onhover
Hover, click or select to translate (with text-to-speech). Translator.
Translate word (or text selection) from any language to the language of your choice by pointing or clicking at it.
Also you can (enable in options):
text-to-speech
reverse translate: from your own language to the language of your choice
type and translate in a popup
copy translation to clipboard
SECURITY EXPLAINED
"Your data on all websites":
TransOver needs to be able to read any word on a page - "Your data ..." - in order to translate it. On any website you want it working - "... on all websites".
"Your tabs and browsing activity":
Required for language autodetect, so that TransOver knows what language to translate from (details http://code.google.com/chrome/extensions/tabs.html#method-detectLanguage).
CHANGE LOG
1.42
Change google translate API url. The old one seems to be getting blocked more and more.
1.41
Fix regression. T&T popup wasn't showing translation.
1.40
Optionally show "translated from" language in a popup. Because source langage autodetect often makes funny choices and then people blame TransOver for incorrect/missing translations. This will hopefully act as a hint to go and change "translate from" option from autodetect to a set language.
