...every time I open Firefox, it insists on opening a tab with instructions how to use it. There does not appear to be an option to prevent this obnoxious behavior.

Perfecto para traducción rápida de palabras, es tremendamente práctico ya que permite la visualización inmediata de la traducción.

I had to disable this add-on due to the fac t that whenever I highlighted anything on a webpage, it thought it was supposed to translate it and it would open up a dialog window. I found this incredibly frustrating. Maybe you should make it so it is activated through the context menu instead. I would REALLY like to have a translation module I can use instead of Google Translate

es excelente, para cuando se quiere leer documentos o foros que están en ingles, y no sabes una frase, lo traduce de inmediato.
En vez de andar abriendo una pagina con google translate, este add on lo hace mucho mas fácil

Super

this add-on support e10s,which is the most important reason i choose it.Besides,its translation results are good,

Un buen complemento para hacer traducciones rapidas

nice but need in line translation option

I like this UI;very good

Very good UI, I love it.
I want to access to the addon's preference view from about:addons page, not from menu icon.

Translate anything you want quickly,easily and accurately without needing to open another window or anything hassling like that.

its is.to.us.it

Ok.

I hope it can support real-time translation and real-time detection of language.Thanks!

The best translate extension for Firefox.
Almost like the original Google Translate for Chrome.
