bad contrast in url bar and some menu

[seniorkiller]

First time using this and for some reason the contrast in some menu look off

one thing that i notice is that this css using firefox theme. when using light theme it looks fine but when i use other dark theme it messed up. side not i recenly move from https://github.com/PROxZIMA/Sweet-Pop css, not sure if it what causing it and not sure if im not uninstall it correctly
