You can pre-populate Google form answers

Google support says:

If you'd like to send respondents a form with some fields already filled in, Google Forms makes it easy. Here's how to pre-populate form answer fields:

1. While working on your form, click the Responses menu, then select Get pre-filled URL.
   
   
2. Fill in any answer fields you'd like to pre-populate.
3. Click Submit.
4. To send the pre-populated form to respondents, use the URL provided.

I copied the URL and made that my bookmark URL

I find that I can't just click "Submit another response", I have to click the bookmark again if I want the pre-filled field.
