Login Issues

I'm having problems logging in...I put in my login info and click the Login button, I get the page that says thanks for logging in and click here if your browser doesn't redirect you. Then it does the redirect to the page I was on but I'm still not logged in. I have to do this several times before I'm actually logged in and able to post. Has anyone else ever had this problem or does anyone know what might be the cause? I'm using firefox.
