Unable to run firefox flatpak

dwl version: 0.4
wlroots version: 0.16.2-1
distro: arch linux

Running flatpak run org.mozilla.firefox doesn't output anything and doesn't start firefox.

I was having the same problem no matter how I installed firefox.
I was to fix it by changing the following area in config.def.h from firefox to something that I don't use like foot

dwl/config.def.h

Lines 13 to 19 in fbd84ac

    
           static const Rule rules[] = { 
        
           	/* app_id     title       tags mask     isfloating   monitor */ 
        
           	/* examples: 
        
           	{ "Gimp",     NULL,       0,            1,           -1 }, 
        
           	*/ 
        
           	{ "firefox",  NULL,       1 << 8,       0,           -1 }, 
        
           };

That section allows you to specify initial configuration for certain apps. Here it says to start Firefox with tag 8 instead of the current tagset.

If that's not what you want, then just remove that line from your config.h. config.def.h is a sample; config.h is meant to be read and edited.

I just tested the default rule after I got waybar working and firefox showed up on tag 9 instead of 8.

If you count them starting with 1, sure. 😉

	static const Rule rules[] = {
	/* app_id title tags mask isfloating monitor */
	/* examples:
	{ "Gimp", NULL, 0, 1, -1 },
	*/
	{ "firefox", NULL, 1 << 8, 0, -1 },
	};
