Es una extención perfecta para traducir palabras o frases completas, es él complemento ideal para traducir muchisimo mejor que cualquier otro. Es super facil de usar y muy recomendable.

It's a great addon. I don't know if this is possible but I would like the ability for this to work in Reader View as well (actually that is pretty essential to me!).

edit:
Actually I would also like to see support for different translators. There is an application on Windows called "QTranslate" where you can switch between different online translators (like i.e. Google Translate/Bing Translate). That way you can cover more words.

this add-on was awesome

Mate Translate: Отличное дополнение! Быстро переводит. Очень просто пользоваться.

In overall I'm happy user of Mate Translate add-on.

What I've found troublesome is Mate's behavior with Jira / Atlasian stack. When editing Atlasian Confluence page, Mate is adding unwanted data at the end of the page. Same when Jira ticket is edited - ticket's description or comment. It does not happen always, but most of the time. With FF and Mate latest release.

Andaba buscando una extension tan buena como el S3 y este hace exactamente lo mismo. Te despliega un botoncito para ver la traduccion sin abrir pestañas ni otra pagina. Excelente trabajo.

Tremendo, el mejor que vi hasta ahora

Polecam ten translator. przetlumaczyl strony z ktorymi nie radzily sobie inne translatory :D:D:D

Brilliant. Work within pages as well, translating on the go, without just sending you to google translate page.

It empowers the capability of word lookup on Firefox significantly.

this app without any doubt the best among translate apps. I have been using over 6 months. I would definitely recommend this app.

Optimale Anwendung. Übersetzt z.B. DCRainmaker Homepage einschl. ellenlanger Kommentare einwandfrei.
