It would be perfect, if it did not need the "access your data for all websites".
I use it anyway because I trust Firefox to check on it, given that it is "Recommended".
This addon saves me so much time.
On one computer I make it translate immediately when I select with the mouse.
On another one, I prefer to click "translate this text".

Previously was using a similar extension but that one is really buggy. This one is really well crafted on the UX, offers user-centred preference which is really sweet.

Great translation tool on Firefox and Chrome with elegant UI.

I hope you can show "definition" of selected word in toolbar pop-up panel.

Excellent, simple et rapide.

Rapide, facile et intuitif....il répond parfaitement à mes attentes ! une traduction instantanée lors de la sélection d'un mot ou d'un texte sur la page consultée .... Topissime !

Тhe most convenient app for quick translation

hi

Please, add pronunciation ability when it translate, also it play pronunciation of selected word.

Dear sienori! Thank for your Simple Translate for Firefox! This is а great addon.
Please, implement this:
1/ When you click on the translation button, the text selection should not disappear. This disorientates the user in the text.
2/ Button "Copy translated text".

الرجاء اضافة امكانية الاستماع الي النطق

Is it possible to translate when you hover over the button?

O MELHOR tradutor para Firefox que testei até agora...
