Gifs not playing

[marceloflix]

I know for sure the extension is the problem because is the only one i got on my browser enabled, but when i uninstall the extension the Gifs starts to work. The first time i notice the problem was on 9gag.com, i hope there's a fix soon cause this extension is pretty awesome, keep the good work!.

It seems gifv and webm are affected as well, hoping for a fix so I can begin using this again.

I tried it on 9gag and there is an error that shows in console:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://9gag.com' is therefore not allowed access.
