Description
Version

Steps to reproduce
Example steps (replace with your own):
- Create test.html and test.py in the same directory.
- paste the following code:
import asyncio
from pathlib import Path
from playwright.async_api import async_playwright
async def main():
_playwright = await async_playwright().start()
_browser = await _playwright.firefox.launch(headless=False)
_context = await _browser.new_context(device_scale_factor=3)
page = await _context.new_page()
_ = await page.goto((Path(__file__).parent / 'test.html').as_uri())
await page.wait_for_load_state('networkidle')
_ = await page.goto('about:blank')
await page.close()
await _browser.close()
return
if __name__ == '__main__':

playwright 1.61.0Expected behavior
There isn't any error.
Actual behavior
raise playwright._impl._errors.Error: Page.goto: Navigation to "about:blank" is interrupted by another navigation to "about:blank"
Additional context
In fact, it's so strange that the page only goto about:blank once, but it raises error navigation to the link while navigating to itself. I understand and it doesn't affect my service if navigating to new service when another one isn't complted. Is there any way to ignore this error?

Moving over to Playwright Core, this seems to be specific to Firefox across past versions, except 1.59, weirdly. I'm looking into it.

Hi, I'm the Playwright bot and I took a first look at this.
Couldn't reproduce it on Linux, so this looks platform-specific (Windows). Simon Knott (@Skn0tt) has already confirmed it's Firefox-only (across versions, oddly except 1.59) and is on it — so this is just extra data on what I tried.
The error comes from Firefox committing its own
about:blanknavigation with a different document id than the one Playwright kicked off, so Playwright sees its navigation replaced and throws "interrupted by another navigation" (frames.ts:732). Only one explicitgoto('about:blank')in your script, so the second one is coming from the engine.What I ran (none reproduced)
1.63.0-next), Firefox, Linuxxvfb-rundeviceScaleFactor: 3+file://page, matching your script; also an 8× loop ofnewContext → goto(file) → waitForLoadState('networkidle') → goto('about:blank')Your repro is Windows 10 + headed Firefox, which I can't match here, so the trigger looks tied to that environment.

Here's the minimum repro I found, it's very straightforward:
Interestingly, while it fails on 1.61, it's fine on 1.62 and #41859 seems to be what fixed it. The fix seems to be related to #39624. I'll commit this test to ensure we don't regress again.
