Bad

Opens the translator in a different tab. Not everybody talks or needs translations from english to spanish : Useless.

Not helpful. I need the translation right on the tab I surfing, not in another tab.

One star can't be more. The feeling is very bad, right click the direct page after the translation to load the error.

Péssimo

I used to like it but not anymore. There is no direct translation with the selected text->right click menu. I can't believe Firefox allows such regressions each time they present them to us as an improvement

Doesn't detect foreign language.
Pointless if I have to know the exact language I'm translating first.
In Options you have a Translate for ( blank) to (blank)
If I put nothing in first blank and EN for english in second, it doesn't work.
If I put ES (for Spanish) in first blank it translate Spanish to english.. but , how the heck is that any good if I don't know language or I need to translate say Dutch?
I have to go into this add-ons settings each time and change language before using.
POINTLESS.

Too simple! I can't see the translation into the original page and I can't change idioms on fly.

Não está funcionando no meu smartphone Moto G 5 e eu instale corretamente. Alguém pode me ajudar?

BAd no work !

Ne fonctionne pas sur Android

No context menu item is present in Firefox 55 on Ubuntu.

Total failure. No context menu for translation.

This is a good example of why the description of add-ons should include which devices it was written for. This does not work on Android devices without an external keyboard as there is no way to right click.
