Please make sure that you know what you are doing by changing the flags. If something goes wrong, you may need to reset your Chrome browser settings or reinstall the browser itself.

Tab Hover Cards Flag

Go to chrome://flags/#tab-hover-cards and flip the menu to Enabled, Enabled B, or Enabled C to enable. If you want to disable, you can select Disable.

You need to restart Chrome browser after you flipped the flags.

Tab Hover Card Images

Go to chrome://flags/#tab-hover-card-images and flip the menu to Enabled, if you want to see the preview thumbnail image in tab hover cards.

Force Dark Mode for Web Contents

Go to chrome://flags/#enable-force-dark to check whether this flag is enabled or not. This flag renders the web page automatically to dark even though the website doesn’t have this feature. There are multiple options available under this flag. Websites may look weird, but if you opt CIELAB-based conversion, renders may look good.
