Please don't make exceptions for sites under the Preferences/Security tab, since strange sites should not be allow to auto-install extensions into your Firefox. I'm not sure what the other exception was... pop-up blocker maybe? '''Assuming you are getting a bar sliding down between the toolbar area and the page with an Allow button for redirects:''' I suggest turning off the redirect warning. It was intended to help users with screen readers avoid confusion when the page changed, and was never intended as and rarely is useful as a security feature. You can turn it off here: Windows: "3-bar" menu button (or Tools menu) > Options Mac: "3-bar" menu button (or Firefox menu) > Preferences In the left column, click Advanced. Then on the right side, make sure the "General" mini-tab is selected. If it is checked, ''uncheck'' the box for "Warn me when websites try to redirect or reload the page" Success?
