    Gradient not being applied

    Hello! I recently got this theme, but the beautiful gradient that, for example, the active tab should have, isn't there.

    I'm pretty sure I have correctly installed Chameleon's Beauty - I have customized the wallpaper of my new tab using it, also, so that's proof that it works. I also have installed and enabled the Beautiful GX Proton theme.

    What am I doing wrong? Why is there no gradient?

    Icon has a glitch on right side for the "Firefox" icon for the theme

    Please see here for an example of this, i believe it's related to 4K display, i've got it sized to 250% as i'm on a laptop.

    Thickness of the bookmark folder border

    Love this theme but I find the thickness of the bookmark folder border kinda ridiculous in the last update. Can you point me to the setting where I can make it as thin as around the settings/hamburger window? Thanks
