Official Firefox add-on bringing offline translation support to Firefox
I've been trying it for a while, it's good for what it is. But it really has some weird UX decisions. One of the weirdest UI(not UX) bugs was supposedly fixed a short while ago, where the translation bar somehow breaks the entire navigation bar of Firefox once you turn on translation. I wonder how this is even possible.<p>An actual UX decision I cannot wrap my head around is that it cannot be turned off once it you used it on a page/language. Maybe the assumption is that language decisions are completely binary. Either you completely understand a language or you absolute don't and will never understand it.
