Debtap make downgrading packages easy on Archlinux

today I updated my system and Floorp is completely break userchrome (again) but this time it's very severe basically it doesn't load userchrome at all, so I look into a way to downgrading it but unsuccessful but I can just download .deb file then convert it to Arch installer with Debtap and install it with usual "paru -Udd" and everything just work. So if you haven't heard of this wonderful software yet I think you should check it out https://github.com/helixarch/debtap
