# Multiple browser profiles

> Multiple browser profile support for the UiPath Extension for Firefox, enabling automation of different profiles using the Use Application/Browser activity.

Starting with UiPath version 2023.10, the UiPath Extension for Firefox supports automating multiple browser instances running with multiple user profiles at the same time.

:::note
Automating multiple browser profiles requires UiPath.UIAutomation.Activities v23.10 or newer and browser extension installed with UiPathStudio.msi v23.10 or newer.

You can specify a browser profile when using the [Use Application/Browser](https://web.archive.org/web/20240105020614mp_/https://docs.uipath.com/activities/other/latest/ui-automation/n-application-card) activity. To do this, append an argument to the browser command line using the **Arguments** property in the **Unified Application Target** input section.

For Firefox, use the following argument: `-profile "full_profile_path"`. To find the profile path, navigate to `about:profiles` and copy the **Root Directory** for the desired profile.
