Best translator for Firefox Mobile!

The best translate extension for Firefox I ever use!
Thank you so much for this work.
Please keep it free and trust me
You'll get the value the you deserve soon

Don't know what exactly some people disliked so much that they even gave it 1 star, but this addon is the best among the other ones for translation.

假开源.

Best bilingual translate add-ons ever!!!
