Are you doing development and need help testing hidden form fields?

Or, just interested in seeing what information the site you are on is passing about you!

Either way, this extension makes it extremely easy to see all hidden form fields on the page.

The extension currently has 2 modes of providing hidden field info:

  1. The HFF Toolbar
  2. JavaScript console logging

These options can each be turned and off through the options page. Additionally, there is a timer in case you want the toolbar to dissappear after a certain amount of time.

Doesn't update when the fields update. Also doesn't show which form tag the hidden fields are in.

Does exactly what it say's it will, love it!
by A Google user, 2014-04-01

It's a fine plugin, but it interacts poorly with some site elements. DoneDone, for example. With this plugin enabled, many elements on DoneDone do not function properly.
