# Firefox (Flathub Flatpak org.mozilla.firefox) on the Frame.
|
|
#
|
|
# vrFullscreenFix: real fullscreen is broken in the Steam session: gamescope
|
|
# gives the fullscreen X11 window input focus but never shows it, so Firefox
|
|
# looks frozen. With ignore-widgets, fullscreen (e.g. YouTube) only fills the
|
|
# Firefox window itself, which in VR can be made as large as you like.
|
|
# Profile names are random, and flakes can't read $HOME at eval time, so the
|
|
# user.js is linked into every existing profile on each switch.
|
|
#
|
|
# desktopProfile: the Steam session and the nested desktop have separate D-Bus
|
|
# buses and displays, so a second Firefox can't find the running one and
|
|
# stops at the locked profile. In the nested desktop (XDG_CURRENT_DESKTOP=KDE)
|
|
# the launcher uses its own profile instead (the launcher creates the dir,
|
|
# Firefox fills it). It gets no user.js: real fullscreen works there.
|
|
#
|
|
# The launcher's desktop entry shadows the Flatpak's own entry (same ID), so
|
|
# MIME/default-browser associations for org.mozilla.firefox.desktop still
|
|
# apply, and the Steam "+" menu (which only reads ~/.local/share/applications)
|
|
# sees it.
