I'm having similar issues with the beta. Lastpass is constantly giving me red banner error warnings at the top of my screen that it cannot connect to the server. Very annoying

I'm having similar issues with many videos on www.digg.com . Some videos play fine but sometimes i have to go to youtube's site directly to view videos and even then it seems to load the player in flash instead of HTML5.

I'm using the mac beta version with VPN
