Can anyone help me with my firefox CSS? I'm a dumbass noob and modified some CSS I got from someone's dotfiles. It's nearly where I want it to be but I have two problems. There's this white line under my tab bar at all times that I can't get rid of, and the "Connecting" text on a tab when loading a new page is aligned lower than the standard text. You can see both in the pic.
Here's my CSS. I know it's a mess.
