perfecto

Это лучшее расширение для быстрого перевода фраз. Раньше пользовался MateTranslate для Firefox, но оно жутко тормозит

Everything is great, but I wish it worked when I select words in pdf files in browser embedded reader.

ik ben een perfectionist en vind Simple Translate: perfect !!!

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.
