It would be better if this add-on can translate words on PDF.

Excellent! Easy, fast, good design. Recommend to all.

Actually the best translation extention hands down.

Efficace, simple d'utilisation et fonctionne sur tous les sites en sélectionnant un mot, une phrase...

1. It's not works on some pages for example "https://addons.mozilla.org/ru/firefox/addon/simple-translate/". It can't translate any word.
2. It has conflicts with Internet Download Manager! Sometimes it hangs next to the IDM download small icon.

simples e fantástico! Alternar entre 2 idiomas é muito bom!
simple and fantastic! Switching between 2 languages is really nice!

Good I like it. easy to translate web,text,online book

A really worthy replace for google translate in Firefox. I loved it.

Very simple to use, it's great because I can change between 2 languages. My mother language is portuguese and I need to write in english with certain frequency, so it's great to check if my spelling is correct :)
