Today I tried to login to my Comcast online account from its first page to see the current bill; and I found that the password field is taking clear text and the text is visible directly as shown in the picture below:

After testing a bit found that it is actually a bug when you focus the mouse on the username field and if you just started at the first character without deleting the whole visible text (username) under the user name field, it just keeps the text as is…what a bad design…
