I’ve been having trouble logging back into WordPress after deleting cookies for my blog domain.

Signing in with valid credentials through wp-login.php reloads the same page. Notice the url redirect in the address bar.

It turns out that every time I delete cookies associated with my blog domain in Firefox on my Mac the domain is added to the cookie exception panel, blocking successful access to the WP admin area. Removing my blog domain from the exception panel clears up the problem.
