UI unresponsive - popups appearing in external Browser

[SethBodine]

Looks like popups are being blocked, but i'm seeing the UI freeze for several seconds when a popup occurs, and when a pop-under/new tab is triggered (presumed via JS) i'm finding rouge tabs open in my external browser.

Both JS and block popups are enabled in the prefs

I noticed the same when the feed has twitter stuff embedded.

hmm noticed under Browser preferences some options gone missing, namely block popups and deactivate javascript.
