I think this is going to be my main translator from now on, even if it certainly needs improvement (I might use another one in specific cases).

Right now, the translation bar is indeed not the most elegant, but the option to hide it is fine.
There's a little icon next to the address bar (which I didn't notice at first) to make it reappear at will.

Oh, and this text was translated seamlessly by Firefox :)

Doesn't have a full page translation feature

Ça me plait bien si c’est plus efficace que l’ancien et si c’est fiable aussi.

Tried on a language I knew well enough to check results and it worked ok. Tried to translate a long comment someone else had made in Spanish and got a mesage about the translation engine failing to load.

Why is there no Arabic translation?

La traduction anglais-français est moins bonne que celle de Mate Translate.
Je le garde quand même mais désactivé, dans l'attente des versions futures de meilleure qualité.

The English-French translation is not as good as Mate Translate.
I keep it anyway but disabled, waiting for future versions of better quality.

flawless

Je trouve ça dommage de ne pas pouvoir choisir quelles sites internet je veux traduire.

Parce qu'on a vite fait de prendre un site anglais, espagnol ou autre pour un site français.

C'est pour ça que je ne suis pas fan de la traduction automatique et lui-préfère de très loin l'ergonomie de Google Chrome.

Faire un clique droit de la souris pour trouver dans le menu contextuel "Traduire en Français" est bien plus adapté à la majorité des usages.

l'extension "S3.Traducteur" de votre catalogue le fait beaucoup mieux que vous avec en plus le choix de personnaliser l'outil du plus minimaliste au plus "Geek".

Nice but... Need option : Translation for selected text. But I like the idea behind the extension... Good work

It seems to work reasonably well on the pages I use most - Spanish. However, some of the scripted boxes, like Buscar (search) don't translate. NOTE the developers' comment about functional errors: "A CPU that supports SSE4.1 extensions is required for this addon to function properly."

Don't work at all.
Add-on well installed but when i want to use it, always an error.
Can't load the module.

The overall concept and translation experience is great. However, the lack of Japanese supports is a deal-breaker for me since the language is supported in both Safari and Chrome built-in translators.
