Finally i found what i want.Bro👍👍👍

parfait ! A+++++

Excellent! Gets it done so far and hoping it remains that way. Please don't fix what isn't broken.

Very useful add-ons, it helps me for Arabic language

Simply perfect!

In detail:
This is a great idea about a primary target language and a secondary target language.
Moreover - wow! - it works recursively: I can select a word in the translation window and translate it back to the original language.
In any case, this addon works fine with a minimum of clicks (this is important to me)
Thanks!

It's not in service very often. I need translation for about dozens of times every day, but it would prompt kind of "reached service limit" from time to time, which is very annoying.

This is the best application to perform rapid translate while reading web page

Best copy Chrome Google Translate in FireFox.

I watch Korean/Chinese streamers on Twitch.tv and this add-on is perfect for translating chat

簡單好用又輕便，這就是我所想要的！

Realmente la mejor extencion que he probado para traducir en Firefox
