Hello theme users,
I've done many adjustments to the theme and been fine-tuning it. The following points are new in the theme:

1. New navigator toolbox design in elementary OS 8 style, and tabs that show separators when they are unfocused.
2. Included accent color values, which work with elementary OS accent colors. Follow number 3 in section After Installation if you have Flatpak Firefox installed and you want the accent colors to work.
3. Changed the readme file to explain how to install packaged Firefox because the accent colors will work out of the box on this installation.
4. Many fine-tuning adjustments like finally some working circled buttons for extensions. Now you can put extensions and other tools in the navigation bar again, selecting them will look good and do not cover the count badge anymore. You can even put all your tool bar icons in the tab bar or the bookmarks bar if you would want that.

Enjoy the new adjustments of the theme!

Note: Epiphany looks different now with the tab bar seperated again from the navigation bar. It is not what I prefer but for this theme I will always try to mimic the style of Epiphany.

Edit: fixed link to After Installation.
