I have been using this extension for a long time. On mobile fennec and in desktop firefox, and more recently also in chrome and edge! (I put it from the "developer mode") This is generally the best extension in the world! Now, after it became available, I put it on the official firefox 120.1.1 on android. Everything is just as great, but until the settings > translations >automatic transfer link leading to the same domain is selected. "Yes" is not available. I think this is because you need a special permission to read the visited domains.

Güzel Eklenti Teşekkürler

This is a great add-on. It gives you all the functionality that is built in to Chrome. Not only does add-on work on Firefox Android, it supports translation from Czech (something that translate built in firefox desktop does not support). For android, I like that it automatically pops asking if you want to translate instead of having to select something. Also, it translates the whole page instead of highlighting text to ask the add-on to translate. Excellent add-on.

Very very good ⭐⭐⭐⭐⭐

One of the best translation add-on!

GOAT

for me the best add on for Firefox mobile, it is what this browser missing a page translate without any inconvenience

WOW, I'm not very often impressed but this extension is top. Translates automatically from Greek to English in no time

It used to be my favorite translator because it was so simple: 1click to translate, 1click to return to the original...

Having neither found the solution nor understood your explanation, I had forbidden the Firefox update, because despite having configured not to update your extension, it was still being updated with the Firefox one. I just tried the FF update again yesterday, (from 119 to 121) and then miracle, the extension works again as before, same update, so I don't know who was guilty, the extension or Firefox. In any case, I'm happy to be able to continue using it.

Unfortunately, no matter what translation service you use, it doesn't work.
Sometimes half a page is translated, but not the rest, and even refreshing not only doesn't change anything, but the translated part is no longer translated.

Esta é a melhor extensão de tradução. Ela traduz páginas inteiras ao simplesmente apertar o botão do idioma no qual você deseja ler. Não é necessário colar uma frase ou texto para depois ir na extensão de traduzir. Essa extensão faz isso de forma automática sem sair da página da web.

This extension works exactly like in Chrome, in realtime. Great.
