How do I resolve the error popup regarding data corruption due to an older version of Firefox when using launch_persistent_context() to load a Firefox profile?

Answer

To resolve the error popup about data corruption due to an older version of Firefox when using launch_persistent_context() to load a Firefox profile, you can follow these steps:

1. Update Firefox

Ensure you have the latest version of Firefox installed on your system. You can download the latest version from the official Firefox website.

2. Create a new Firefox profile

Instead of using an existing profile, create a new one to avoid compatibility issues. To create a new profile, follow these steps:

  • Open Firefox
  • Go to about:profiles in the address bar
  • Click on "Create a New Profile" and follow the instructions

3. Use the new profile with @playwright/test

Now that you have a new profile, you can use it with launch_persistent_context() in your @playwright/test script. Here's an example:

import { test, expect } from '@playwright/test';

test('Load Firefox profile', async ({ browser }) => {
  const userDataDir = '/path/to/your/new/profile';
  const context = await browser.newContext({
    storageState: userDataDir,
  });

  const page = await context.newPage();
  await page.goto('https://ray.run/');
  // Your test code here
  await context.close();
});

Remember to replace /path/to/your/new/profile with the actual path to your new Firefox profile.

By following these steps, you should be able to avoid the error popup and successfully load your new Firefox profile with @playwright/test.

Thank you!
