Класc. Есть и гугловский переводчик и яндексовский.

Melhor tradutor automatico para firefox.

Funciona excelente, esta bien integrado, funciona al igual que chrome. 100% recomendado.

Fonctionne à merveille

The best translator. Very fast

Это шикарное расширение! работает отлично!!!!

The FASTEST and most UNOBTRUSIVE translation plugin. I am also very pleased with the support of DeepL

Super handy addon!
The only downside is that it doesn't keep translating the page in case content changes due to javascript or something. But still 5 stars because of it's usefulness!

good software 👌👌👌

Por lo poco que lo usé, funciona bien!!!
