I'm experiencing problems when playing a video on my Facebook Newsfeed. After about 10 seconds or so the video stops playing and the whole site freezes. This does not affect other open tabs nor does Opera crash. The frozen tab can be closed without problems.
Mac OS X 10.11.6
Same version same as problem on windows
Same issue on Windows 7.
Same for me. Noticed it this morning 5/11/2017
Video plays about 1/3 and then stops and the whole tab freezes. Clicking on the x of the tab will eventually kill the tab while the rest of Opera and remaining tabs work just fine. This is new. I am an everyday Opera and Facebook user.
I've noticed the same problem. The newest Opera version - Facebook on normal page and on Fanpage likes to freeze. Quite often
They still didn't fix this?
Try with a Private window and / or a clean profile, Mac steps (despite the mess).
If rebuild needed:
OMenu > Help > Find Solutions >> Backup your Opera files
Try cleaning site cookies and cache if Private window works.
