The extension works unreliably and there is no indication as to what went wrong. You can't click on the extension to force translate as in google translate.
This is one feature for which I switched to chrome long time ago and this is still an issue with Firefox.

Doesn't work at all.

Nothing happens when you press it on address bar. It's very slow on the phone and not convenient at all, because you need to choose the language every single time.

Broken and defunct, can't add languages in FF to translate to (2025, Nov. 15)

seems to be currently broken.

Регулярно обновляю Firefox. Раньше при просмотре комментариев в Youtube на различных языках под комментариями была надпись "перевести", что было очень удобно. При посещении зарубежных сайтов Firefox переводил автоматически сайт определяя язык. С каждым разом обновления стало только хуже!!! Функция перевода комментариев в Youtube через браузер Firefox исчезла! При установке Firefox Translations кроме появившейся иконки перевода А она не работает и не определяет язык!!! ВСЕ СТАЛО ТОЛЬКО ХУЖЕ!!! Всю жизнь пользовался Firefox к которому привык, но придется похоже переходить на другой браузер. Для меня Firefox - УМЕР!!!

Add-on Doesn't Work nor does the built in Firefox browser translation functions that supposedly replaced the Add-on. Clearly Mozilla doesn't know what they're doing when it comes to translations and should just leave it to Google and Chrome as translation just works inside of the Chrome browser.

It doesn't work in any way. I am using Firefox 142.0 x64 on windows. It does nothing when you press on the address bar and neither directly to extension.

En Linux: 141.0.3 (64-bit), No puedo creer que no funcione, el icono de la barra de dirección ni el de herramientas, a no ser que desde el menú elijas "traducir página." En cambio en W11 la misma versión ya viene la extensión por defecto y operativa. Una pena.

It doesn't work at all, click on icon does nothing, so it's totally unusable (on FF 140.0.4 64 bit). Moreover, it does not support the language I want to translate to. So I tried it so you wouldn't have to.

Ich würde mich sehr freen wenn die Handhabng etwas erleichterter wäre

It is all blank and can't be used.

Já tenho usado há alguns meses e tem me servido muito bem. Nunca tive problemas.
