Changes:

• Light/dark theme support
• Rounded corners (including browser content window)
• Identity badge colors
• Floating link popup, rounded corners
• Context menu theming, also removed unused entries (personalized to me)
• Expand vertical tabs on hover (using Firefox's built in vertical tabs)
• Hide Specific toolbar buttons (personalized to me)
• Iconic Firefox (https://gist.github.com/emvaized/a379d61ed8970e5711ca7278a39c1895)

To-Do:

• Adjust shadow darnkess/colors in light theme
• Find a way to keep the Firefox vertical tabs always expanded (Will randomly revert to compact mode)
• Find a way to restore drop shadows under sidebar and browser content windows.
  • Currently, the side bar must have z-index:4 in order to maintain proper animations with my CSS. However, this places it above the sidebar and brower content window.
  • This will cut off any shadows that go under the vertical tabs bar (aka, any shadows to the left ofthe sidebar/browser content window).
  • Possible solution to look into: delay on :not:hover and return the z-index to a lower number? That way the animation can complete when not hovered and it can return to a lower z-index.
