Google translate no longer showing up when I mouse over blue words
I have same problem too.
This happened to me for about an hour a few days ago. But it started working again later. Have you tried logging out and back in? It’s currently working for me.
Thanks for the heads up. It seems to be acting a bit strangely at the moment, working for some words but not for others. We’ll look into this.
Weird, for some words it doesn’t show up for a bit, and then does show up a few seconds later if you go back to the word.
I was about to post a topic about this when my power went out. 
Google Translate seems to be working fine now. We haven’t changed anything here since the update, so these issues must be coming from Google’s end.
