Most Videos Won't Play in Newest Opera 18
Ok, on top of there not being bookmarks any longer, this newest "update" makes about 80% of all videos I've attempted to view, impossible. What's up with that?
http://blogs.opera.com/desktop/2013/12/youtube-is-back/ Please read this. Restart the browser, after couple of minutes patch should be applied. If that doesn't help - locate your profile directory - on Windows it's %appdata%\Roaming\Opera Software\Opera Stable, on Mac delete ~/Library/Application Support/com.operasoftware.Opera/- and delete the browser.js file. Restart browser again, after 1-2 minutes file should be downloaded. We will remove the patch once YouTube will rollout their fixed version.
thanks mmitek, but it seems to now work ok... maybe YouTube fixed whatever was causing it.
