Removed rounded corners on tabs and urlbar (Firefox nightly 156 Linux)

[olen]

I have disabled the new Nova UI  .... Not to my taste 

After some search & testing I have nearly manage to get rid of the rounded corners on the urlbar.

Is it possible to get rid those rounded corners  completely ?

From my userChrome.css

#urlbar {
font-size: 16pt !important;
outline: 3px solid #000000 !important;
}

#urlbar-background {
outline-offset: 0 !important;
border-radius: 0px !important;
box-shadow: none !important;
background-color: black !important;
}

Try adding this:

    * {
      border-radius: 0 !important;
    }

    @media -moz-pref("browser.nova.enabled") {
      :root {
       --chrome-window-gap: 0 !important;
      --chrome-block-radius: 0 !important;
      --chrome-content-separator-color: transparent !important;
      }
    }

Interesting.

To my userChrome.css it was enough to add 

* {
border-radius: 0 !important;
}

It removed the rounded corner from tabs and the urlbar.

Thx for the info 🙂
