The latest development version of Google Chrome has added a much required feature, called Form AutoFill. This was one of the most requested feature from the missing Google Toolbar for other browsers like IE and Firefox.
Just like the Google Toolbar, Google Chrome now allows you to set up profiles and enter Addresses and Credit cards details which you can then use to fill out long and inane forms :-).
AutoFill is enabled by default in Chrome dev v5.0.356.0. You can also add profiles and enable or disable the AutoFill settings by visiting Options -> Personal Stuff.
