{% embed url="<https://www.youtube.com/watch?v=VcuVuomhaUs>" %}

Incogniton lets you install custom Chrome-compatible extensions into your browser profiles. This allows you to optimize each profile for your specific workflow, without sacrificing fingerprint protection or anonymity - whether you’re running automation tools, managing ads, blocking trackers, or handling multiple accounts.

In this guide, we’ll walk you through the steps to upload a custom extension and assign it to profiles. Before you begin, ensure the custom extension file you want to upload is saved on your computer and in **.crx format**.
