@burnout426 OK then.

@burnout426 Thanks! I've always been leery of root commands. I'm about to update to Mint 19 so I'll make sure to remember this. Your fix worked very well. Appreciate the time and trouble.

@burnout426 tried it in the terminal and it said it couldn't find the file. Not sure how to launch the file manager like you suggested.

@rhawk Tried extracting it to that location but it said permission denied as well as trying to paste it to that folder. Didn't even ask for my password. Not sure what to do now.

@burnout426 OK then.

@burnout426 Should I try that or not. Also, I thought the 'sudo' was a command for use in the terminal. As I stated I'm not well versed on Linux.

It's been like this since the update before the one to 54. I had hopes that 54 would fix it but it didn't. No animated Gifs, No videos. It sucks and I wish there was a simple way to fix it other than forcing me to use Firefox.

MPEG-4 ASP, H.264, and H.265 no longer work on Oprea most recent update. I'm using 54.0.2952.46 on Linux Mint 18.1 (x86_64; X-Cinnamon). Prior to the last 2 updates I used Opera for almost everything. Now Facebook and Twitter along with most of YouTube are basically broken. What is the easiest way to fix this, with simple instructions please. I've tried following some of the other fixes suggested but really don't think I can do them correctly. Firefox became too bloated and slow for me but I'll go back to it if I have to. I don't want to.

I have the same problem. Updated yesterday and since then ZERO videos work. I was able to get a few to work by using an addon called YouTube Flash HTML5. It seems that HTML5 is what is causing the biggest problem. BTW, all these videos work on both Chrome and Firefox. I really like Opera and have been using it as my main browser. I'd really hate to have to switch back, but I can't watch any videos on Facebook posts, nor animated Gifs! It's very frustrating.

@leocg OK then. Thanks. Wish they'd bring those kinds of settings back. Appreciate the prompt response.

@leocg So these settings no longer exist? This is from a video from last year, not 5 years ago:
