Try adding: EWMHIgnoreStateHints Doesn't help: $ grep Firefox ~/.fvwm/config Style Firefox EWMHIgnoreStateHints, FixedPPosition, SkipMapping Style Firefox PositionPlacement 0p $[_WINDOW_TOP_]p, StartsOnPage 0 0 1 $ FvwmCommand 'Read config' $ nohup firefox > /dev/null 2>&1 & $ This still immediately leaves the current page and displays page "0 1" instead, where I can watch Firefox unfolding, and never goes back to the original page. Regarding EMWH I found the following in "man fvwm": -V | --version Prints the version of fvwm to stderr. Also prints an information about the compiled in support for readline, rplay, stroke, xpm, png, svg, GNOME hints, EWMH hints, session management, bidirectional text, multibyte characters, xinerama and Xft aa font rendering. So I did $ fvwm -V fvwm 2.6.5 compiled on Sep 28 2019 at 11:15:46 with support for: ReadLine, XPM, PNG, SVG, Shape, XShm, SM, XRender, XCursor, XFT, NLS fvwm comes with NO WARRANTY, to the extent permitted by law. You may redistribute copies of fvwm under the terms of the GNU General Public License. For more information about these matters, see the file named COPYING. $ but without finding any hint regarding EWMH. So maybe it's not config- ured in my version of "fvwm". But then, Gentoo doesn't offer any USE flags for "fvwm" which suggest having to do with EWMH support. What next? Sincerely, Rainer
