It doesn't seem to work properly with me, have tried via Google Chrome but it doesn't feature any of the plugins you added, is it still working?

That's weird my friend, I just try with 3 browsers and all of them give the translate option, here is the image:
But i realize the site needs to load 100% and after that, the translate bar comes on the top, your problem could be the loading time or a cache problem. Try with a hard refresh (ctrl+f5) and then wait until the site loads. And if it doesn't work then try with another browser and that should fix the problem.
