Just today when I opened private browsing tab on my firefox it opened a new separate window and an icon appeared on the taskbar unlike before where the private window would be one with the firefox icon on the taskbar. I tried the fix of editing the config '''browser.privateWindowSeparation.enabled '''and turned it to false but still it did not work. I also disabled all my studies but it still is the same. I have attached several screenshots about the problem and solutions I tried.
