Vocabulary Boost

Big parts of the web are in English. While reading articles or blog entries, user comments or forum posts, instructions, tutorials or problem solutions you may stumble upon unknown words. With Vocabulary Boost you can simply hit Ctrl + Double Click on the unfamiliar word and get an instant translation into your native language. If you want to practice the newly learned vocabulary later, you can add it to your training set and exercise with flashcards.
This way you will easily expand your English vocabulary.
