How to pass profile preferences to the browser?

We recommend that you read the Getting started with Kameleo Automation article before reading this one.

With Kameleo you can fine-tune the browsers and you can pass most of the options, and preferences that are supported by the browsers. You need to start the browser with POST /profiles/{guid}/start endpoint and pass preferences and additionalOptions to it. See the documentation on SwaggerHub.

You can set a list of preferences for browsers at startup. In the case of Chromium-based browsers, it will be a user profile preference. In the case of Firefox profiles, it will be a preference.

You can also set a list of additional options at startup. These are values that are defined by our team.

This way you can simply save network traffic by disabling images.

• await client.startProfileWithOptions(profile.id, {
    body: {
      preferences: [
        {
          key: 'profile.managed_default_content_settings.images',
          value: 2,
        },
      ],
      additionalOptions: [
        {
          key: 'disableTouchEmulation',
          value: true,
        },
      ],
    },
  });

  See full example here.

• await client.StartProfileWithOptionsAsync(profile.Id, new WebDriverSettings
  {
    Preferences = new List<Preference>
    {
      new Preference("profile.managed_default_content_settings.images", 2),
    },
    AdditionalOptions = new List<Preference>
    {
      new Preference("disableTouchEmulation", true),
    }
  });

  See full example here.

• client.start_profile_with_options(profile.id, WebDriverSettings(
    preferences=[
      Preference(key='profile.managed_default_content_settings.images', value=2),
    ],
    additional_options=[
      Preference(key="disableTouchEmulation", value=True)
    ]
  ))

Please note that some preferences may be blacklisted as they may interfere with Kameleo’s spoofing mechanism.
