Issue opening file in Flatpak-based browser about opener

[Seeker14491]

The opener crate delegates to xdg-open on Linux. Not sure what I can do here.

I was running into this same issue.

On my system, xdg-open is configured to run the flatpak version of Firefox. I suspect that whatever logic is doing this is taking the one html file passed on the command line and sandboxing it into a temporary directory, then passing that to Firefox. I don't know if this is a bug or a WAI from the point of view of flatpak.

I also found https://wiki.debian.org/DefaultWebBrowser#Opening_the_default_browser_from_a_script. So, at least on Debian systems, it is most "sensible" to open a browser with sensible-browser instead of xdg-open. On my system, sensible-browser ends up running gnome-www-browser, which also works when run directly.

pprof, a program run by Google, does something completely different that has always worked for me (but hard codes a preference for Chrome...): https://github.com/google/pprof/blob/f7f687d19a9829062f02a2dd6e9a6fb527dbf143/internal/driver/commands.go#L354

So, my workaround is running commands like gnome-www-browser target/doc/whatever/index.html directory.

The current contens of the sensible-browser script, on a Debian 12 system, is this:

#!/bin/sh

# Prevent recursive loops, where these values are set to this script
p="$(command -v "$0")"
[ -n "$BROWSER" ] && [ "$(command -v "$BROWSER" || true)" = "$p" ] && BROWSER=

IsError()
{
	# Operating system command not found
	[ "$1" -ne 126 ] && [ $1 -ne 127 ]
}

Run()
{
	"$@"
	ret=$?
	IsError "$ret"
}

if test -n "$BROWSER"; then
    Run "${BROWSER}" "$@" && exit "$ret"
fi

if test -n "$DISPLAY"; then
    if test -n "$GNOME_DESKTOP_SESSION_ID"; then
        if test -x /usr/bin/gnome-www-browser; then
            exec /usr/bin/gnome-www-browser "$@"
        elif test -x /usr/bin/x-www-browser; then
            exec /usr/bin/x-www-browser "$@"
        elif test -x /usr/bin/gnome-terminal && test -x /usr/bin/www-browser; then
            exec /usr/bin/gnome-terminal -x /usr/bin/www-browser "$@"
        fi
    fi
    if test -x /usr/bin/x-www-browser; then
        exec /usr/bin/x-www-browser "$@"
    elif test -x /usr/bin/x-terminal-emulator && test -x /usr/bin/www-browser; then
        exec /usr/bin/x-terminal-emulator -x /usr/bin/www-browser "$@"
    fi
elif test -x /usr/bin/www-browser; then
    exec /usr/bin/www-browser "$@"
fi

echo "Couldn't find a suitable web browser!\n" >&2
echo "Set the BROWSER environment variable to your desired browser.\n" >&2
exit 1;
