On Ubuntu all applications adhere to a behavior where when you mouse middle button click on empty spot on window top boarder the window is supposed to stay open yet lower itself behind all other open windows.

Standard ff version 65 works fine on current Ubuntu 18.10 so do all other applications

ff nightly used to work until version 66 and 67 ... its been broken a few weeks on ff nightly Is this a bug or did it somehow get disabled and put under a flag in about:config ?

I booked a ticket here with zero response :

Are you possibly using code in userChrome.css that could cause this?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
