I'm experiencing a crash on Opera since the last few updates. I'm currently using Opera 46.0.2597.57 in Mac OS X 10.12.5 64-bit.
I'd like to add that when a video is being played at Facebook and you start to scroll down, when the video starts to hide, a "pop-up" video will appear (that's the new implementation of Facebook). Sadly, Opera crashes as soon as this implementation try to appear. I don't know if this is the right place to put this bug, but when Opera crashes it doesn't show a message for reporting a bug. It just restart and then show a top-bar with a message "Opera crashed".
I hope devs would see this message.
