FormFill Assistant per LoadingCounter

FormFill Assistant suggests values as you click or type into form fields, based on a personal profile you configure yourself.

Open the sidebar, add your fields (First Name, Email, Phone, Address, etc.), and the extension will suggest matching values whenever you interact with a form on any website. Suggestions appear in a small dropdown under the active field and can be selected by click or keyboard.

Each field can have comma-separated aliases/alternate names used for matching. For example, a "First Name" field with aliases fname, given name will match form fields labeled any of those ways.

All data is stored locally using Firefox's built-in storage. Nothing is synced, transmitted, or shared.
