I use in Ubuntu to TTS (Text to Speach) on websites, the OS system lector Ubuntu is like a robot. Firefox has no built-in voice, uses the OS system. Unfortunately, the Imtranslator has a limit of up to 100 characters.

Probé todos los traductores, este es el mejor, el mas rápido, mas limpio, con varios proveedores, traducción en linea de texto seleccionado y completamente gratis!! RECOMENDADÍSIMO!!

Best translation plugin in firefox.

Excelente traductor, aunque a ultimas semanas falla un poco espero su pronto arreglo.

It's great! A few requests though:
1. Disable it on form fields (usernames, passwords, etc.)
2. Ability to choose where the pop-up should show (and also resize it)
3. More than one language as target language

Good

สุดยอด....extension แปลภาษา

The best translator I've used.
Quite easy use,powerful,multiple functions,etc.

The best for Firefox......Bom bisurdo...

This is what I looking for. Pop-up translator. Thanks!!
