# Extensions & Cookies

#### Extensions

You can add extensions to a profile from the Chrome Web Store or from a custom extension file.

{% tabs %}
{% tab title="Webstore" %}
Add a Chrome Web Store extension to your profile with the following steps:

1. Copy the Chrome Web Store URL for the extension you want to use.
2. Paste the URL into the field provided using this format: `https://chrome.google.com/webstore/detail/extension-name/id`
3. Select **Add** to save the extension to your **Webstore library**.
   {% endtab %}

{% tab title="Custom" %}
Custom extensions let you add an unpacked extension folder or a packaged `.crx` file instead of pulling from the Chrome Web Store via the following steps:

1. Select **Select folder** or **Select .crx file**.
2. Enter a name. If you choose a folder, the name auto-fills.
3. Add an optional description.
4. Select **Add**.
5. Find the extension in the **Custom library**, then add it to the profile.

{% hint style="info" %}
Custom extensions are only available on paid plans. On the base plan, this tab shows an upgrade prompt instead of the form above.
{% endhint %}
{% endtab %}
{% endtabs %}

Once added, extensions appear in the **Assigned to this profile** list, where you can use **Remove selected** or **Remove all** to remove them. All your extensions are also available under **Browsers > Extensions**, where you can view and manage them across all profiles.<br>

{% hint style="info" %}
Installed extensions form part of a profile's fingerprint, and may be visible to websites. Always consider whether an extension fits the browser environment the profile is intended to represent before adding it.
{% endhint %}

#### Import cookies

Import a saved cookie session into this profile using one of the following formats:

<table><thead><tr><th width="257.6328125">Format</th><th>Description</th></tr></thead><tbody><tr><td>JSON</td><td>Standard JSON cookie export, used by extensions such as EditThisCookie and Cookie-Editor.</td></tr><tr><td>Netscape</td><td>Plain-text cookies.txt format, commonly produced by curl and older export tools.</td></tr><tr><td>Base64 JSON</td><td>Base64-encoded JSON cookie blob.</td></tr><tr><td>Base64 Netscape</td><td>Base64-encoded Netscape cookies.txt.</td></tr></tbody></table>

Select the format that matches your source, then paste the cookie data. The Base64 formats are decoded automatically on import.

{% hint style="info" %}
This page only covers **how to** **import cookies from the Edit profile panel**. For more in-depth cookie guides, including exporting, cleaning, converting, and generating cookies, see [Cookie management](/cookie-management/importing-cookies.md).
