Sometimes, when js or flash or something is lagging\loading, the page can't be closed, and if i try to close it, it waiting for something, i think there is no consequenses for closing an js script when it's running.
The same problem with page refresh, buggy javascripts don't allow browser to refresh.
Also, i need an ability to remove "heightened security" for domains like google.com.
Sorry for my bad english, btw
