User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:127.0) Gecko/20100101 Firefox/127.0
Steps to reproduce:
In https://bugzilla.mozilla.org/show_bug.cgi?id=1795931 it was explained that
browser.privateWindowSeparation.enabled can be toggled to keep grouping normal and private windows in the Windows taskbar, which is my preferred behaviour.
Actual results:
As of, Firefox 127, this behaviour no longer works. Private windows are at a completely different place my in Windows 10 taskbar compared to normal windows.
Expected results:
Private windows should appear in the same window group as normal windows.
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:127.0) Gecko/20100101 Firefox/127.0
Same problem here. Firefox just updated itself to version 127.0 and now private windows open with a separate icon in my taskbar although browser.privateWindowSeparation.enabled
is still set to false. Please fix this! Thanks in advance!

Is this safe enough for uplift?
(There is a lot of clamor to restore this feature, e.g., https://connect.mozilla.org/t5/ideas/bring-back-the-option-to-group-the-private-and-normal-firefox/idi-p/59173)

I reproduced this issue on an affected Nightly build from 2024-06-11 on Windows 10.
Verified as fixed on Windows 10 and Windows 11 using Firefox 128.0b5 (20240619092300) and Firefox Nightly 129.0a1 (20240620040816). With browser.privateWindowSeparation.enabled set to false, there is no separate taskbar icon; normal and private windows are grouped under one icon.
On Ubuntu and macOS, regardless of the state of the pref, there is only one icon for both normal and private windows. Is this expected?
Even though I am pretty sure this is a Windows-specific issue, could you please confirm so I can mark this as verified?

Thank you for testing, yes this is a Windows-specific issue. This pref is not applicable for macOS and Linux.
