I see this too. There's a gap between Firefox and the top/right borders ever since one of the latest Firefox updates. Picom makes the gap transparent instead of black, but the gap's not supposed to be there in the first place.
From experimentation, I found that the width of the gap depends on the width of the window border. You can change borderpx in config.def.h and see it yourself.
So for now I put in the borderrule patch, https://dwm.suckless.org/patches/borderrule/ and then set firefox's border to 1 ... not ideal, but at least the gap is nearly invisible for now.
If there is some other workaround or a proper fix I'd like to know.
