Modify look of Firefox 89 tabs

Firefox 89 has a new design of tabs.

Here's my quick & dirty take to bring traditional-looking tabs back.
It involves creating <profile_path>/chrome/userChrome.css like one below.

1) round top borders

/* userChrome.css */

.tab-background {
    border-radius: var(--tab-border-radius) var(--tab-border-radius) 0 0 !important;
    margin-block: var(--proton-tab-block-margin) 0 !important;
}

2) flat

/* userChrome.css */

.tab-background {
    border-radius: 0 !important;
    margin-block: 0 !important;
}

Hah, interesting! Thx for sharing!

I see it changes some other bits about toolbars here and there, some menus too.
Haven't been for the humongous X (close) buttons on tabs I would use it permanently.
