How does the backdrop filter work?

The backdrop filter in Firefox is a CSS property that lets you add visual effects to your web page like blur or color filters to the background of the design. Because the filter is added to the entire background of the design, the effect will be visible only when you make the design or its backdrop somewhat transparent. You can also refer to the MDN Web Docs by the Mozilla developer support for the basics of how to apply a backdrop filter to your element. However, if the backdrop filter is still not working in Firefox version 102.0, you may need to re-enable the preferences in config as explained above.
