Quiero la traducción en un pop-up, no en una pestaña nueva. Si quisiera una pestaña con el sitio translate de google, la abro yo mismo.

No traduce la pagina

Would be great if it could translate on the same page

翻譯時會出現" %20 " 已移除

Why use this at all? Just keep open a tab on Google Translate instead. Or better yet, find an extension that actually does inline translations. There's a few on Firefox Addons.

it doesnt translate the language after you change the main one spanish

請ADD zh-TW 繁體中文語系

this is add-on is very bad :(

Mi traduce in spagnolo, mentre io vorrei la traduzione in italiano.

Good
