Preloading Firefox for quicker load time

[Swefton]

I've noticed that if I have a Firefox window open, then opening a new window is far quicker than starting from scratch. I wanted to find out if there's a way to keep Firefox running in the background for this quick startup.

I tried using Preload to mixed results, it was working for a bit but then the service wouldn't start and it kept giving trouble.

I was wondering if an alternative approach could be leaving Firefox running in a hyprland tray or some other alternative?

Firefox does not use SNI, so it can't be left in a tray. Best solution is to use Preload. Alternatively, try starting firefox in a clean profile and see what extensions and settings you can disable/configure from your usual profile to make it load faster.

Minimize to system didn't work, I tried following the Steam Solution but firefox wouldn't close nor minimize.

if [ "$(hyprctl activewindow -j | jq -r ".class")" = "Steam" ]; then
    xdotool getactivewindow windowunmap
else
    hyprctl dispatch killactive ""
fi

I suppose I'll stick to the preload solution.
