Try as I might this will not translate a page of any language. Enter the URL in the box, select languages and then nothing happens when loading.

As being an Indian , I haven't found our National language HINDI . So i want you to include languages like Hindi and Telugu for translation.

I want to have the option to select a piece of text and translate without leaving the page I'm on instead of translating the whole page

Mi dispiace dirlo perchè voglio bene ai sviluppatori di Mozilla, adoro Firefox e le sue estensioni ma purtroppo questa estensione è una schifezza e sembra sviluppata da principianti. Lo dico veramente con dispiacere ma per me è così.

please add chinese

still did not support Arabic language.

No Chinese

works fine, if youre learning russian not for memes

We want to translate into Arabic

I've used the Firefox translator for probably 5 years. As a French teacher and somewhat competent in Spanish, I have found this program to be quite competent.

En la traducción en español no esta del todo pulida pero si sirve, se nota mucho los errores en muchas veces.

Does not work with Firefox on Linux: "Une erreur s'est produite lors du chargement du moteur de traduction"

no japanese or chinese support >:(

It would be useful to add the translator by right-clicking on the page, rather than taking up space at the top of the screen (or leave the choice to the user).
For the moment, it's really bothering me, but I'm going to wait a while to see future updates, because the tool itself works pretty well.
