Answer 1

If the theme for KDE is Mojave Dark, then set the theme for GTK.
1. Go to the settings, select the item in the drop-down menu of downloads: download GTK3 themes
2. Install McMojave theme, dropdown menu item: mojave-dark.tar.xz
3. Install this theme for GTK 2-3 applications, check the box to prefer dark themes:
4. In the browser in the tab bar, right-click to uncheck the box: use system frames and title bar (stylized theme buttons will appear on the right), we need it on the left, the Gnomish tweaker (because it's GTK) for some reason does not move them to the left, so we edit settings.ini file along the path .config/gtk-3.0, add the line there:
5. Restart the browser if it was open.
