There are two ways to install a browser extension or a plugin into Multilogin browser profiles. This article explains how to do it.

Using browser interface

This method is the same as installing extensions in regular browsers. We recommend using it as a primary method and only refer to the second one if it doesn't work for your use case.

  1. Start your browser profile
  2. Visit Chrome web store if you use Mimic or Firefox browser add-ons page if you use Stealthfox
  3. Choose your extension and click "Add to Chrome" or "Add to Firefox"
  4. You will see the installed extension in the top right corner of the browser profile window

Using browser settings

With this method, you can pre-load any browser extensions or plugins into Multilogin profiles, including custom ones.

These steps need to be completed on every device where you plan to use Multilogin with browser extensions or plugins.
