2)Run the following testcase with firefox browser through vs code. (Make sure to check the checkbox for "Show Browser").

3)Inspect the network tab of the firefox browser for any websocket connections.

Expected behavior

Actual behavior

The websocket requests cannot be seen in the network tab of the firefox browser, can be seen in chromium though.

Additional context

Though these requests cannot be seen, the application works without any issues. Meaning, the requests are being sent in the background but just cannot be seen in the network tab.

This looks like something you want to bring up with Firefox team. I'm opening that page in FF and see no WS in their network panel.

I do see the websocket request in the normal firefox browser. These requests are not seen when the firefox browser is launched from playwright.

Yep, I can repro, was opening using npx playwright out of habit.
