Cannot set browser.link.open_newwindow preference

[Gerald94]

System

• Version: 0.33.0
• Platform: Windows 10
• Firefox: 114.0.2
• Selenium: 7.4.1 + 3.141.59

In my testcase i click an link and i want that the link always opens in a new tab instead of a new window.

In my capabilites i want to set the preference:

option = new FirefoxOptions(); option.addPreference("browser.link.open_newwindow", 3);

When i execute the test i get the following error:

Preference browser.link.open_newwindow may not be overridden: frozen value=2, requested value=3

Does anybody know how to fix that?

Could you please attach a trace-level log from geckodriver? Read more about reporting actionable bugs in our contribution guidelines.

Actually which binding of Selenium is that? I can see references to that in the Selenium repository: https://github.com/search?q=repo%3ASeleniumHQ%2Fselenium+%22frozen+value%22&type=code

Ok, so I think that this is a Selenium issue and that you should use Selenium 4 to get it working.

Oh i think you are right. But for me it is no possible to switch to Selenium 4 now, this takes some time.

Is it somehow possible to set this preference fixed in geckodriver or firefox? As a fast workaround?

You would have to ask the Selenium folks if there would be a workaround. Maybe use that formerly mentioned issue for that.

Thank you so much for the help.
