Firefox opens a new Window when a new tab was expected

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

Hello folks,
I am having a KSE issue where Firefox opens a new Window when a new tab was expected.

Test steps:

  1. Manually open Firefox and navigate to our AUT website
  2. Log into the site
  3. Click any link from within the AUT website

Result: The expected page loads in a new tab

  1. Start Katalon and run a TC that does the following:
  2. Open Firefox and navigate to our AUT website
  3. Log into the site
  4. Click any link from within the AUT website

Result: The expected page loads BUT in a new Window
Note: This works as expected for both Chrome and Edge Chromium.

I have searched the web/Katalon Forum for Desired Capabilities to force a new tab to open but have not had any luck. Can someone please point me to a possible solution.

I guess you already know this… the default is likely this setting:

Sorry, I don’t know the Capabilities setting (if you find it, please post it).

Here you go - let me know…

Found it.

The setting (the same as the about:config setting) is browser.link.open_newwindow.

You want to set it to the value 3.

Excellent. Thanks Dave.

Would you mind posting the above as a Tips article? I’d do it myself but I don’t want to steal your thunder :wink:

Leave the original intact, but take a copy and massage the text to suit a new tips topic.

Thanks!
