Extension that helps translate Russian words in web pages to English

ЛЕКСИКА! – Russian Vocabulary Tool is a simple extension for all websites. It enables you to easily translate and to get a quick dictionary of any Russian word. The extension automatically scans every website you visit for English-Russian word pairs in its dictionary (currently contains over 800 word pairs) and replaces the English with Russian translations.

In the settings, you can enable the extension for a given website only once. You can also change the number and difficulty of the Russian words used. Additionally, there is an option to disable the extension and the website completely. You can also enable the option to see the list of words for that website.
