I created a new version of this add-on
https://addons.mozilla.org/en-US/firefox/addon/page-translator-3/

closest thing to google translate in chrome !!!!

It was working perfectly on my last Firefox for Android. However with the last update 89.1.1 is not working anymore. If you guys could fix it would be awesome! Thanks for your work! :)
EDIT: it is still working in the version 67, you can download here: https://archive.mozilla.org/pub/mobile/releases/67.0/

Funciona no Android. Traduz página inteira no Google de imediato. 1 clique.

Simple, works fine and integrates with browser in right way! Thanks!

The only translator today works to taste Chinese webpages to English

Excellent minimalist add-on that does exactly what it says. This should be built into Firefox.

Um dos melhores para Firefox, e que também funciona na versão Android (PS.: só funciona na versão Neghtly usando o modo desenvolvedor e coleções personalizadas)

i searched for all website translate plugins but this is the only one i found. Each and every other extension is giving an option to translate text.. this gives option to translate pages.. amazing work

Wrong perfectly.. Translated page in complete sentences not word to word. Thats cooool

This is about as close as it gets to the translate feature on Chrome as far as I have seen - I like Firefox and pretty much the only reason I keep going back to Chrome is the in-page translation feature. I may have found an amicable solution to this conundrum.
