how to uninstall "./tweaks.sh" firefox gtk customization

I wanted to customize Ubuntu with WhiteSur theme. Found this githup repo that lets me do that. I customized firefox with their ./tweaks.sh -f command. Now I want to remove that customization (kind of looks bloated). How do i do that?


Close Firefox Browser, Then Delete the code inside the file ~/.mozilla/firefox/firefox-themes/userChrome.css

Restart Firefox.

You will see the default look of Firefox
