Some of you may experience problems logging in using the Firefox browser.
From the Wordpress Forums…
“To fix this error, go to Firefox Preferences > Security > Choose What Warning Messages to Show, then choose to show all warning messages. Try to log in again, and when the warning message appears (it wasn’t before), just click Continue.”
OR
“Must be some weird cookie issue with Firefox. My WordPress was working fine until I upgraded to 2.5.1 but then I started having this problem.
It seems to work fine if I use: http://mywebsite.com/wp-login
as opposed to: http://www.mywebsite.com/wp-login”
