I've never imagined nor have I actually seen such a service! And it is so smart, picking up what I need to be translated.Wow!

Il manque plus qu'une petite option dans les paramètres pour redimensionner la fenêtre quand elle s'ouvre pour la traduction et là elle sera plus que parfaite.

Poderia ser mais bonito!

This extension has an ugly "speech bubble" icon in firefox — please go back to the pretty blue "google translate" icon picture.

EDIT (reply to dev response): then why is the blue icon still all over the extension's firefox addon website? I was surprised when I downloaded the extension and was surprisingly confronted with another icon. If it's good enough to lure users with it then it should be good enough to be available in the users' interface.

Good but, it not include spelling for each word.
And it not work in private mode.
Please fix these problem, thank you so much.

The only extension that actually lets you translate text in a pop-up balloon above the text. I recommend turning all the other options off by the way, so that rightclick menu only has the balloon option, the others are much more intrusive, I also had to turn off the annoying auto translate when hovering mouse, and the menu is a little confusing to be honest. But its great to have options !! good work dev!

The way the pop-up bubble function has been implemented (and how it can be customised) makes this the most convenient and easy-to-use translation tool for my needs and the best translation extension I've come across. In truth I don't really need any of the other functions. However, I have noticed that this extension is consistently shown at the top for energy impact in about:performance, sometimes even higher than video playback, so something is always running in the background even if there is no functionality in use and even if the pop-up button is disabled. I really hope this gets worked on.

The core functions are very well built and work as intended. Just the UI has a lot to be desired. The settings UI is even worse, it is very confusing and doesn't lay out what each option does nor do they all work as intended.

For future, I would like to have certain language pairs always coupled with a certain translation provider. Like for example Chinese to English is miles better on Bing but the UI first always makes me see the bad translation of Google.

Wunderbar, nun muss nicht extra jedesmal ein neuer Tab für den Google Übersetzer geöffnet werden...

good
