This Chrome extension allows pre-filling form fields via URL hash parameters. Useful for websites that don't provide a way to pre-fill their form fields.
For example if the page www.logistics.com/track
has the following field
<label for="tid">Tracking number(s)</label><br>
<input type="text" id="tid" name="tracking-id"><br>
You can prefill it by referencing its name in the URL hash
www.logistics.com/track#tracking-id=123456789
