This isn't going to be the most important tip I've ever shared here, but as it is annoys the you know what out of me, I thought I'd share. I fill out a lot of forms, and one of the first things I do on a form is double click in the first field to give autocomplete a chance to fill in as many fields as possible. Unfortunately, sometimes this isn't possible because the site creator, for whatever reason (maybe even a good one) decided to disable this.
Autocomplete can be disabled at both the form level and the field level. To disable it for the entire form, you would do:
<form action="iwantyoutowastetimeenteringcrap" method="post" autocomplete="off">
To disable it on a field by field basis, you would simply use the same attribute in the field itself:
<input type="text" name="iwantyoutotype" autocomplete="off">
As I said, maybe you have a good reason for this. Wufoo seems to do this by default for their forms. However, this bothers me. I'm seeing it being used in forms that have nothing necessarily private/secure in them and it just annoys me. So here is a 30-second video showing how to quickly get around it in Chrome's Dev Tools. You can do the exact same thing in your browser of choice.
Now if I could only apply autocomplete to all the various medical forms that require me to enter the same information multiple times my life would be complete.
p.s. As another tip - please don't ask for someone's birthday and their age. You don't need both.
