Prevent Form Field Autocomplete
Preventing autocompletion of form fields is incredibly important since we never know where our users are completing them from. They could complete them from a super secure computer or an incredibly public computer. Regardless of security level, some field values should never be remembered, like credit card number, social security number, etc. Preventing autocompletion is as simple as adding one attribute to a FORM tag for individual form fields.
The HTML
The autocomplete attribute is the key. This attribute may be added FORM tags to prevent any autocompletion:
<form method="post" autocomplete="off">
You may also isolate single fields for preventing autocompletion:
<input type="text" name="credit_card" autocomplete="off" />
Big detail, simple task, simple solution.

MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does. Many developers create their classes as globals which is generally frowned up. I mostly disagree with that stance, but each to their own. In any event...

One thing I love about love about Safari on the iPhone is that Safari provides a darkened background effect when you click a link. It's the most subtle of details but just enforces than an action is taking place. So why not implement that...

One of my guilty pleasures is scoping out the latest celebrity gossip from PerezHilton.com, DListed.com, and JoBlo.com. Unfortunately, these sites occasionally post NSFW pictures which makes checking these sites on lunch a huge gamble -- a trip to HR's office could be just a click away.

its a bad idea to make users type out their email id, name etc on every website. There’s a reason why autocomplete was invented.
As I stated, there are credit card numbers, social security numbers, passwords, etc. Those shouldn’t be remembered.
Passwords should be remembered IF users want to them of be remembered.
There is a bug about that in Chromium:

Until it’s fixed, there is an add-on for this:
By using the feature, websites force me to use this add-on, which could decrease my security.
Sorry, the add-on is: https://chrome.google.com/webstore/detail/autocomplete-on/ecpgkdflcnofdbbkiggklcfmgbnbabhh
