When I open the Log on page in my Bank website and enter my username and password, three times out of five the page is re-directed normally to the accounts page, but the other two times I get the "Firefox prevented the site from re-directing to another page" error. I click allow, and all works normally, but it sometimes takes me time to wake up to the cause of the delay,given that we have slow Satellite internet anyway. I, too, would like to make an exception to my "prevent re-direction...." command for selected websites.
