Steps to reproduce:
Right clicked on WIN 10 taskbar. Selected "Cascade Windows" from the options prompt.
Actual results:

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Win32' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Could you run mozregression to see when this started happening?
A number of Firefox versions will open in succession to narrow down when this started occurring. Simply answer "good" or "bad" based on whether or not a build reproduces the bug. Once finished, please post the output from the last run. It should give a last good and first bad revision as well as a link to look at the changesets in that range. Thank you!
Running mozregression is beyond my skill set.
As an example, if you open Firefox and multiple MS365 apps (e.g. Excel, Word, PowerPoint) and then right click on the WIN10 taskbar to select "Cascade Windows" option from the menu prompt, you will see that the MS365 windows cascade but he Firefox window does not cascade.

Would running the regression tool still be useful? I've never used mozregression but I could try it if it would help. As the issue with cascading/stacking windows still persists in Windows 10.

Redirect a needinfo that is pending on an inactive user to the triage owner.
:rkraesig, since the bug has recent activity, could you have a look please?
For more information, please visit BugBot documentation.
So I ran mozregression tool with builds from two years ago (2023-08-21) to today. And never got the Cascade bug; Show windows Stacked/Side by Side also worked.
Figured it must be a plugin, so I ran my regular Firefox and opened a Private window. Tried the windows Cascade option. And as expected, the Private window obeyed the Cascade command correctly, but the regular Firefox window did not.
I'm going to turn off plugins and see which one is the culprit.

If I close all Firefox windows. Then use the option via Firefox icon to "Launch a new Private window", that Private window will properly Cascade when prompted. Then if I use that Private window to open a new Regular window, then the regular window will properly Cascade as well!
The problem only seems to affect the first Regular window.

Thanks for the additional investigation! I can repro on 116.0.3 Release, but not on a current Nightly. (If we're lucky, that means this has been fixed as a side effect of something else in the last two months, but I'm not going to assume that yet.)
FWIW Firefox 121.0 (64bit) has this issue.
Windows 10 Pro 22H2 - right click on taskbar "Cascade Windows", "Show Windows Stacked", "Show Windows Side by Side" appear to be ignored completely by Firefox window opened in window mode middle of screen while other windows on the desktop do respond.
