Set Firefox Profile

Set a custom Firefox profile or use an existing profile for your tests that run on Firefox browsers in BrowserStack Automate.

Overview

Firefox profiles include custom preferences that you would like to simulate an environment for your test script. For example, you might want to create a profile that sets preferences to handle the download popup programmatically during your test run.

The following sections include sample code snippets to create a profile or use an existing profile with preferences that handle the download popup and succesfully downloads the file.

Check out the available preferences at the MozillaZine Knowledge Base.

In this guide, you will learn about:

Use an existing Firefox profile

Using an existing profile from your local machine involves the following steps:

  1. Creating the Firefox profile locally
  2. Setting the Firefox profile in test scripts

Create the Firefox profile locally

  1. In the Firefox browser, enter about:profiles in the address bar.
  2. Create a new profile and click Launch profile in new browser.
  3. Enter about:config in the address bar
  4. Search for the following preferences in the search bar. If a preference is not autopopulated, you can add it manually.
    • browser.download.showWhenStarting to false
    • browser.download.folderList to 1
    • browser.download.manager.focusWhenStarting to false
    • browser.download.useDownloadDir to true
    • browser.helperApps.alwaysAsk.force to false
    • browser.download.manager.alertOnEXEOpen to false
    • browser.download.manager.closeWhenDone to true
    • browser.download.manager.showAlertOnComplete to false
    • browser.download.manager.useWindow to false
    • browser.helperApps.neverAsk.saveToDisk to application/octet-stream

Check out the official Mozilla documentation for detailed information.
