Mouse FlyOver translation doesn't work anymore

Except English, this app does not have Text To Speech for other languages.

It would help if the author would spell out the languages in which this app works (translate & TTS)
OS: Linux (Ubuntu)
Browser: Firefox

🇬🇧 It's a must have for those who want to learn another language without having a full translation. click (or stay over) a word and after small delay, the translation of this word appears in a popup.
However, sometime, translation could be wrong ("Inflation rose and economic activity slowed": rose was translated as a color 'rosé' and not as a verb (rise))
🇨🇵 C'est une extension indispensable pour ceux qui veulent apprendre un langage sans avoir la traduction de toute la page. En cliquant (ou passant la souris sur) un mot, après un petit délai, le mot apparaît dans un popup.
Restez vigilant, parfois la traduction peut-être fausse ("Inflation rose and economic activity slowed": rose a été traduit comme 'rosé' et non comme un verbe)

The the program is great when it is working properly. The service is often erratic!

Good! Small but detailed enough and not obstructive.

very useful

Waited for too long for you baby...

Absolutely love this add on. So incredibly convenient and useful. Thanks so much to the developer. iirc there used to be a software that could run on your PC, so not only an addon in Firefox or Chrome but would work on everything. I wish that became available again.

Rápido y sencillo, traducción instantánea de palabras sueltas o frase, sin tener que gestionar ventanas, un pop up informativo que aparece, te dá la información que necesitas y desaparece sin molestar.
Una herramienta que no se hace de notar porque funciona como tiene que funcionar una buena herramienta, de manera transparente.
Gracias!.

Escribo esto 10 meses después de la primera review: La traducción al español es una pasada, una sobrada, deja la traducción de google tiritando. Ojalá se pudiera traducir una página entera con este plugin, porque, este SI merece la pena.

this add-on is so convenient, I used to have a translator tab always open and always had to switch back and forth to it for every single word i didn't understand.
with this it had saved me tons of time and effort
I honestly expect such an app to have hundreds of thousands of users
i don't know what translation engine exactly it uses but it does even a better job than googles own translator
and its open source!
