This plugin has just been launched and is currently in beta for the Persian language. However, it works reasonably well.
My opinion is do not decide too soon.
Every big change needs support and time, thanks to the hard-working Firefox team

"Development: Russian <-> English" — waiting.

It is pretty decent I would like an option to disable the big translation bar and stop asking me for translate every website I visit, also a popup menu like google translate extension or a context menu entry would be way better and less intrusive.

Pas encore très fonctionnel mais une très bonne initiative !

No Bangla, No Japanese. Useless

Does nothing. Just shows sometimes "fxtranslation-notification" on the yellow ribbon and thats all.

I think the problem is Firefox ESR last version. 4 star for when my ESR version is updated or this plugin is updated.

«There are two more planned releases of Firefox 91 ESR and then it will go out of support on September 20, 2022. Users will then be automatically upgraded to the Firefox 102 ESR.»

works pretty damn well, reminds me of chrome but firefox and local!

I've been looking forward to the day I could try the results of "project Bergamot" in Firefox. The fact that translations are made client-side is great for privacy-minded users (and should be put forward as an USP when marketing this add-on!).

Regarding this add-on: my first impression is that translations (tried German -> English and Portuguese -> English) are of a high quality. Possible errors are highlighted in red: good idea.

I think the UX still needs some polishing, hence the 4 stars. Why just copy-paste Chrome's translation bar? I wouldn't mind a floating, less vertical space consuming toolbar (like we have in Firefox's Reader View). Also: some options are still missing (translate only a fragment, switch back to original text, no manual found, no preferences found ...). A progress bar would also be clearer than the number of elements remaining to be translated.

But very promising for a first release, and I hope more languages will be added soon! I'd also like to contribute to (improving) Dutch translations.

Tiene errores al traducir.
No contiene una opción para volver al idioma original.

Manchmal werden die Webseiten nicht vollständig Übersetzt, aber an sich super Erweiterung und 100% Lokal.

addon yang bagus, masih perlu banyak dikembangkan dan ditambah banyak bahasa lagi 👍
