Extension not working in FireFox on 1 computer but works on another

@"jack.platten" @ag_yaron I replied to the email just now, but I wanted to update the public thread as well. It turns out that I was mistaken in my OP. Both I and my coworker are actually experiencing the bug exactly as described. I thought the Enter key wasn't working on her computer, but that's apparently because she or I had clicked on the arrow first, which took the focus off the password field (and the Enter key only works when the focus is in the password field). And I must not have been trying the arrow key on my computer, because I see now that clicking the arrow doesn't work on my computer either. Sorry for the confusion!
