# Multiple browser profiles

> 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.
:::
Opening the browser with a specific profile is now possible 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 specify a profile at browser start-up, you must append an argument to the browser command line. To do so, use the **Arguments** property in the **Unified Application Target** input section.For Firefox, the required argument is: `-profile "full_profile_path"`. To retrieve the full profile path, navigate to `about:profiles` and retrieve the **Root Directory** for that profile.
