Was this ever resolved? When clicking a link on Facebook and Twitter a new tab is created but not loading. It doesn't matter what version of Opera but here's what I have currently.
Version: 37.0.2171.0 - Opera is up to date
NO extensions are loaded.
I use this Chrome extension. There are a few settings to go through to get it to delete data on exit. One small downside, you have to close the browser window (red x in top left) for it to work before exiting the browser (cmd Q). Better than forever waiting for a native feature.
