This was unobtrusive, easy enough to use and translated quite well IF.... IF you could get it to work, and that was the failure when translating a whole page. In the very beginning, I had the add-on translate something from French to Dutch, and from then on, that was the default setting when translating an entire page, it would auto-fill to translate from French to Dutch OR, once-in-awhile, from Dutch to Dutch, and it couldn't be changed. Sometimes I could change the translate to language to my native English....sometimes.....but I could never get it to detect the language it was supposed to translate FROM. I'd try to guess what the original language was so I could manually set it....that didn't work, usually because I didn't know what the original language was and wasn't going to go through all 90+ choices hoping to hit the right one. I'd set it "detect language" and it did absolutely nothing...NOTHING happened. I tried to find where to reset the default settings to see if I could undo the default it had set for itself from the beginning....no such option, at least nothing I could find. So, unless I was just translating a few words or a paragraph or two that I could copy and paste into that part of the add-on function, it was worthless since there was no way to detect or manually set the original language when trying to translate a whole web page. I removed the add-on and will look for another. VERY DISAPPOINTED!

Todos los traductores que he visto dan pena en su funcionamiento poco funcional. Este no es la excepción, muy deficiente, límitado y lento. Hasta ahora usaba el S3.translator, el único que he visto que traduce las páginas web sin perder el formato, y con undo instantaneo además de ser casi invisible en su funcionamiento, es MUY superior a estos programitas que se arrastran con sus limitaciones de uso. Son todos casi iguales y los programadores no brillan por su inteligencia al aplicarlos en una página web completa. El problema es que al S3 ya no lo veo más en Firefox, pero creo que está en Chrome. Quizas sea tiempo de migrar a Chrome, no por el navegador en sí, sino porque necesito la funcionalidad que me da un traductor como el S3.

Раньше было лучше. Всплывающая кнопка с переводом прям поверх иностранного языка самоый лучший вариант.

Good addon, but I accidentally switched to a "classic" style and there is no way to go back. I've even tried uninstalling and reinstalling it, and there's nothing in the addon options that refers to such a feature.

I rather prefer the add-on Panel View for Google™ Translate because it allows a floating button over the word you mark.
