FieldFiller by mh03r932

Fill every form control on a page with plausible dummy data in one action. Respects the form's own validation constraints, reaches iframes and shadow roots, and makes no network request of any kind — no account, no tracking, no server.

About this extension
FieldFiller has a single purpose: to populate form controls on a web page with generated
placeholder data, on the user's explicit command, so that developers and QA engineers can
test forms without typing values by hand.

Every feature in the extension serves that goal. The options page configures how
values are generated and which fields are filled. The context menu and keyboard shortcuts
choose how much of the page to fill. The export and import features move that configuration
between the user's own machines. The extension does nothing else — it does not read, store
or transmit page content, and it takes no action unless the user triggers a fill.
