Getting the right info when you relocate can be vital. This add-ons saved my behind more than once. THX Filipe!

absolutely useful

Don't know why this extension has such high ratings. Settings interface is horrible jumbled.

Use this one instead of To Google Translate which provides highly outdated/clunky translations. Plus no opening some kind of separate window or page is required, just a pop-up, yay, and with the function of text-to-speech.

Extensão muito boa, pois em alguns sites, o tradutor original dos navegadores dá um refresh para traduzir o site. A extensão permite você desativar e ativar o tradutor como bem entender, lembrando que ele tem opção de traduzir apenas uma frase do texto, caso desejar. Bom para ter o aprendizado de aprender outra lingua e a facilidade de tirar dúvidas na tradução de palavras desconhecidas.

garbadge, half page is translated other half isn't

Google translate works well here but there are simpler extensions for that. Google's translations are average. I couldn't get Bing to work here. Yandex works but is worse than other options. Using DeepL just opens a new tab and pushes your text over to the new tab which I can do myself with copy paste. DeepL won't let you translate a whole webpage for free, only text snippets. DeepL is poor at names, idioms, titles, and short bits of text but really good at longer form texts.

This is a nice extension with good customization hindered by poor translation tools. For my purposes its better just to use something simpler.
