@shtrom Excellent. I was trying to find out if this existed recently but couldn't figure out the URL — it's not yet listed in about:about !

The old Firefox translations extension had a pop-up widget on the toolbar, but that disappeared when translations were integrated in the core browser. And this is much easier to use, anyway. Limited languages so far, but once it has downloaded the language models, it runs offline.

@shtrom See, I knew that Firefox could translate websites, but I didn't realise it also had a front-end for translating whatever I wanted!

@shtrom works offline too!
