I’m running n8n locally and when I click “Execute Workflow” on my Form node it shows “Listening for a test form submission,” but no test form tab ever opens

I’ve set up n8n via Docker on localhost:5678 and configured a simple Form node. After hitting Execute Workflow, the node status changes to “Waiting for you to submit the form,” yet my browser never spawns the test form tab—even with pop-ups enabled.
Has anyone encountered this behavior or can suggest what I might be missing to get the test form to open?

Is there another form window or tab open? Sometimes, when you “Execute workflow,” it doesn’t come to the front but stays in the background.

Could you tell me which button you are clicking?

There is a big one at the bottom of the workflow, one to the left of the Trigger Node when you hover over it, and the “Execute step” button when the Node is open for editing.

The two “Execute Workflow” buttons always work for me and open a new window with the form each time.

The “Execute Step” button, however, does not. It seems to check if a window is already open. This is most similar to the behavior you described.


This is what I’m able to see. I’m clicking the “Execute Workflow” button.

If for whatever reason the form doesnt popup in a new tab, you can simply double click the form node and click on the test url which is presented at the top of the node properties and open this in a new window
