First, create a folder named `chrome` inside your profile's directory (you can look up where your profile's folder is in `about:support`). Create a file named `userChrome.css` inside the `chrome` directory. You will come back to this file later.
Go to `about:config` and switch the `toolkit.legacyUserProfileCustomizations.stylesheets` to true.
Open the Inspect element window anywhere, press F1, then tick both `Enable browser chrome and add-on debugging toolboxes` and `Enable remote debugging` options under Advanced Settings.
You can now press `Ctrl+Shift+Alt+I` to open an inspect window for the browser itself.
Finally, you can use this inspector to see what CSS rules affect the UI and change the `userChrome.css` file accordingly.
Every CSS rule must have the `!important` keyword. I highly recommend you use the builtin editor under the `Style Editor` tab in the inspect element window. That way, you won't have to restart the browser the see your changes.
