Changing the titlebar color on MacOS

[kocane]

Hello!

Do you know if it's possible to change the titlebar (tabbar) background color on the MacOS version? I'm using light mode.

As far as I know, MacOS does not allow you to control the color of title bars. However, you can set an accent color.

#TabsToolbar
{
    background-color: AccentColor !important;
    color: AccentColorText !important;
    --toolbarbutton-icon-fill: currentColor !important;
}

Seemed to work. Thanks!

@QNetITQ by the way, does WaveFox enable the transparency in the titlebar on v125 as well? It's my understanding it's a 126 beta thing, but I can't seem to disable it in 125 with WaveFox. I can't confirm it but I'm having pretty severe animation lag when going into mission control, resizing and minimizing and I'm unsure if it's caused by this effect.

On MacOS, transparency is enabled by the style only on the system theme. Starting from version 126, the style no longer contains a transparency code. Now it is provided by Mozilla. Two keys are available. One includes a new effect - Tinting. If you additionally turn on the second key, then Vibrancy should be activated.

Yeah it definitely performs better in 126, that's for sure. Do you know if it's at all possible to manipulate the color of this new titlebar? e.g. make it dark in color?

[QNetITQ]

If the system does not allow this, then styles, as always. The accent color code should still work.

Gotcha. I've changed the style to something dark, while using light theme. However, there's this very bright border on top of the window. Do you know if it's possible to change this via CSS? I believe it's a classic MacOS thing but I didn't notice this on 125.

I don't know.
