When you fill in personal information on a web form, the Silk browser will prompt you to save the information to a profile on your Kindle. The next time you start to fill out web form, your Kindle will suggest a profile by showing you information in a text box. Tap the profile and the rest of the form will be filled out automatically.
You can view and edit your Autofill profiles at any time by going to your Silk Browser settings. This feature can be used to create additional profiles.
If you don’t want to save personal information on your Kindle, you can turn off the prompt by disabling Form Autofill in the Silk Browser settings. Also, this feature won’t work on any website where the publisher has disabled Form Autofill.
