Waiting for About:Blank
About:Blank is the address in many browsers for a navigation placeholder page. It is normally 100% blank, as the name would suggest. However, some browsers may have some features to assist users in navigation, such as the “You’ve opened a new tab!” page.
At any rate, you shouldn’t have to wait for a “blank” page, and it definitely should not take over 30 seconds to come up, which is exactly what happened here.
