Why do I get the message that my browser is trying to block me from logging out of a website properly and to close my browser?

When I log into my online banking and then log out, I get a pop-up message that says my browser is trying to block me from logging out properly and recommends closing my browser to maintain security. This does not happen on any other website I log into.

its probably because of some kind of javascript that your online bank is trying to run when you click on log out. Firefox might consider the browser dangerous while your bank thinks that the script necessary. Nothing to worry about you are completely safe.

Windows 7, Firefox 4.0. I have the exact same problem. Those solutions had no effect, I still get the error message described by OP.

And I also get "Firefox prevented this page from automatically redirecting to another page" as well as when I look at this page http://www.wbir.com/weather/radar/local/default.aspx I get "Firefox has prevented this page from automatically reloading"

I know of tools/options/general/accessibility/warn me when..., but I don't want to turn that off for all sites. Is there a way to whitelist trusted sites so only those sites will be allowed to automatically reload and redirect?
