Description : I try to enjoy the maximum out of web browsing, navigating to pages with media content (flash and HTML5 multimedia content, GIF images, GIFV, etc.) but Opera seems to read and play them correctly on a schedule or logic that escapes me.

Steps to reproduce : Clicking the play button to start playback of videos on Facebook, music from Bandcamp, CBC Music, Ici Musique, Soundcloud, GIF videos from Imgur, or GIF animations on Facebook. Activating or deactivating Adguard has little effect, except displaying more or less blue on my computer screen.

Actual result: Sometimes, contents just seems to take forever to load. Sometimes, the play button does not appear. Sometimes it is unresponsive. Sometimes, it just works. If the latter is the case, I go to a local library and grab a couple of books about magic in order to learn the mechanics of Internet browsing on the World Wide Webs, so that I would enjoy a movie about the behaviour of young cats or a catchy tune from my favourite sitar player without a browser malfunction causing me to cite every word that has been blacklisted by the Roman Catholic Church since the Western Schism.

Expected result: Media content on web pages are expected to play, unless Facebook is full of lies about videos it contains and I am a victim of a worldwide conspiracy where everyone around me is programmed to make me think procrastination is ok.

OS: Xubuntu 16.04.2 LTS on a 4.4.0-64-generic Linux kernel with a cup of black joe yes that's it no cream no sugar thanks
