why termux version of firefox doesn't have CSD?

[OrchidLuna]

i'm looking at the difference between firefox in termux and firefox in regular linux distros, and i was like "wow, the unified window controls to it's toolbar is so cool!" but late realization that's the exact thing termux's version of firefox don't have, even when using xfce4 DE too.

Firefox on Arch Linux with XFCE

Firefox on Termux also with XFCE. The window contol buttons isn't unified here.

Client Side Decorations (CSD) are pretty much only a thing GNOME/GTK does.

The standard for everything else is server side decorations with CSDs available if an application advertises that it would prefer it's own decorations.
CSDs do allow for those extended titlebars, so if an application makes use of them it will usually advertise to the display server that it would like to provide its own window decorations.

So is it because termux' limitations, i guess? Because the distinct differences are that linux distros have a display manager and both that and the desktop environment is started via init system. while for termux, everything is started on the command line and don't use a display manager.

CSDs should work just fine on Termux.
But you may need to manually enable them in Firefox.

But the only results I can find for it are like 6 to 7 years old.

@OrchidLuna sorry for delay, I was trying to respond ASAP but I accidentally forgot to.

I do know how to do this in Termux, but unfortunately it's a bit inconvenient for some reason, maybe there is a way to write a patch for some package to make it automatic eventually (though it should be noted that some people might prefer the current default, not sure which mode of Firefox is more popular overall)

Step 2. use the command firefox in that same terminal

thanks very much, this works in my current setup with vnc too. put export GTK_CSD=1 in ~/.bashrc, change browser.tabs.InTitlebar from 2 to 1, and restart everything. yay!
