Tip for configuring Firefox (geckodriver) to open NEW tabs

System used:
Katalon Studio Version:
KSE 8.2.5, Build 208
Windows 10 Enterprise (64-bit)
Firefox: 97.0.1 (64-bit)

Tip for configuring Firefox to open NEW tabs.

  1. Open Katalon > Project > Settings Desired Capabilities > Web UI > Firefox
  2. Input the following DC:
{"FIREFOX_DRIVER":{"moz:firefoxOptions":{"args":{"browser.link.open_newwindow":3.0}}}}

See Desired Capabilities for details.
Thanks to @Russ_Thomas for pointing me in the right direction for this solution.

For people (okay, geeks) interested in the dirty details, almost all prefs are available in the Firefox source file here:

This is the same info you’ll see when typing about:config into the Firefox address bar.
