Panlatin Browser Extension for Romanization and Detailing

So you know a bit of many languages and you don't have time to be really fluent?
While reading the web, the computer can show texts in Latin letters next to native words or instead of them. If dictionary is available, translations can be shown, too.

Chinese from "中国位于东亚。" to "中国Zhōngguó 位于wèiyù 东亚Dōngyà。"
Russian from "Столица России - Москва." to "Stolitsa Rossii - Moskva."
Arabic has only transliteration, no dictionary for vowels is available: from "يتدفق النيل عبر مصر." to "ītdfq ālnīl ʻbr mṣr.".

Several display formats and transliteration systems are available. See description at http://panlatin.blogspot.si/2017/04/panlatin-browser-extension.html
