Seems to work perfectly nowerdays (2022) even the "Translate this page" functionality that was not working.
If you use uMatrix and the like be sure to check the allowed domains so fe. gstatic is allowed scripts *on the translated page/tab*.

Спасибо! Я столько всего перерыл и наконец нашёл!

Perfect. Works for both, translate the selected text and translate the whole page.
