I've been looking into moving over to Firefox from Brave and have added some hardening to Firefox. I think I may have done a bit too much but I'm not sure what to change. Brave and others render the terminal output fine but FF shows up like the pic attached. Anyone happen to know what I need to change to get it to show correctly? Thanks!!
It ended up being the canvas settings which I totally overlooked. I was able to allow it on the site using lckdscl's link.
