With the latest firefox update, it will no longer start on my 2nd monitor. I have to drag it to my 2nd monitor. Why?

Let me update this. Firefox always starts in my "main display". I want it to start on my other monitor.

hi, do you happen to have privacy.resistFingerprinting set to true in about:config?

does it make a difference when you set browser.startup.blankWindow in about:config to false?

That fixed it. Thanks!
