Jest bardzo przydatny i bardzo dobrze tłumaczy

It's a good and very useful add-on, thank you.
It'd be great to have the toolbar icon back, I have been using it all the time.

Hope they will put back the toolbar icon.
Until it's there, you can use "Google Translator Lite" ( https://mzl.la/2UlrbIo ), it adds the icon and a context menu item to translate the entire page. But it doesn't translate your selection.

Best Translate Ever!

Why all this hate people!? I've been using this add-on for a couple of years and it always worked properly! It stopped working for a week and you bombard the add-on with one-star reviews? WTF! Have some respect for the developer!

An issue was opened on github and the dev said that the problem is fixed and the addon will work as soon as firefox shows the green light.

For now, you can make the add-on to work by going in -> Manage Extension - Preferences - Open in -> New Tab

Hola! muchas gracias por contestar! pero me gustaría preguntarte porque eliminaste la opción de traducir en la misma página...era un detalle muy bueno, un saludo!

Aquellos que están esperando a que cargue la traducción en la pequeña ventana, les sugiero que vayan a opciones y en lugar de abrir en "modal" seleccionen la "nueva pestaña" y listo! Seguirá traduciendo a la perfección

This Pugin Help me a Lot as my English Is Weak
This Is My BLog
