I've used this extension for a while. Recently however, the Russian translation seems worse than before. Many words "translate" only to their English pronunciation rather than their English meaning. Ex. кадр translates to kadr. In fairness, if the whole sentence is translated, then кадр has a real translation. The extension also used to give several possible translations.

Translation is good, but it screws the layout on some sites

Does what it supposed to and does it well. However it do seem to break some elements on a few pages, with strange line-breaks.

Dysfonctionnement avec la page d'accueil de Prime vidéo, vignettes de film instables difficiles à sélectionner avec la souris. Dommage , c'est un bon traducteur.
