Setup Firefox css

In the searchbar type about:config. A dialog will be shown to you. Press the I accept the risk button.
Search for toolkit.legacyUserProfileCustomizations.stylesheets, layers.acceleration.force-enabled, gfx.webrender.all, and svg.context-properties.content.enabled. Change them to True
Go to your Firefox profile:
    If you're on Linux: $HOME/.mozilla/firefox/XXXXXXX.default-release/
    If you're on Windows: C:\Users\<USERNAME>\AppData\Roaming\Mozilla\Firefox\Profiles\XXXXXXX.default-XXXXXX
    If you're on MacOS: Users/<USERNAME>/Library/Application Support/Firefox/Profiles/XXXXXXX.default-XXXXXXX
Create a folder and name it chrome (with lowercase).
Then paste the all of the files into the folder.
You'll need to enable Title Bar in "Customize Toolbar" (found by right clicking tab bar)

You should also set Firefox to "compact" and "dark mode". Those two options are available under menu > customize. In my case I have installed the firefox theme HUMBLE GRUVBOX, it is the one I have instead of "dark mode", you can get it in "Add-ons and themes". Startpage

For the home page open firefox and drag the index.html file from "/home/XXXX/.firefox/XXXXXXX.default-release/chrome/startpage/index.html". Close firefox and open it again, whenever you open it, it will come out with the home page, Amy works that way for me. Enjoy!
