Please, include a native feature to black out all images and videos on any page. Blocked images (or videos) would only be displayed after some intentional user action. This feature would be very helpful for those browsing in corporate environments who want a more discreet, content-focused experience, without visual clutter, distractions, or inappropriate images. There are currently some extensions that do something similar, but they have undesirable permissions and are not actively monitored by Mozilla. Thank you!
