Quick answer

To fix the Browser Use 'element not found' error, ensure you have installed playwright and run playwright install chromium to install the browser. Use the correct browser_use.Agent class and await agent.run() for interaction. Missing browser binaries or incorrect usage cause this error.

PREREQUISITES

Python 3.8+
OpenAI API key (free tier works)
pip install browser-use playwright
playwright install chromium

Setup

Install the browser-use package and the playwright dependency. Then install the Chromium browser binaries required for automation.

bash

pip install browser-use playwright
playwright install chromium

output

Collecting browser-use
  Downloading browser_use-1.0.0-py3-none-any.whl (10 kB)
Collecting playwright
  Downloading playwright-1.35.0-py3-none-manylinux1_x86_64.whl (1.2 MB)
Installing collected packages: playwright, browser-use

[Playwright] Installing browsers...
Chromium installed successfully.

Step by step

Use the browser_use.Agent class correctly with an async function. Always await agent.run() to perform the browsing task. This example searches Google for 'AI news' and prints the result.

python

from browser_use import Agent
from langchain_openai import ChatOpenAI
import asyncio

async def main():
    agent = Agent(
        task="Go to google.com and search for 'AI news'",
        llm=ChatOpenAI(model="gpt-4o", temperature=0)
    )
    result = await agent.run()
    print(result)

if __name__ == "__main__":
    asyncio.run(main())

output

AI news search results summary or page content printed here

Common variations

Use different LLM models by changing ChatOpenAI(model="gpt-4o") to another supported model.
Run the agent synchronously by wrapping async calls if needed.
Enable verbose logging in playwright to debug element issues.

Troubleshooting

If you see 'element not found', verify playwright install chromium was run successfully.
Check that the task string targets existing page elements or valid URLs.
Update browser-use and playwright to latest versions.
Use playwright debugging tools to inspect selectors.

✅

Key Takeaways

Always install Chromium with playwright to avoid 'element not found' errors.
Use async/await with browser_use.Agent and call agent.run() properly.
Verify your browsing task targets valid elements or URLs to prevent failures.
