Black Box Content Hider

not working. macbook air. os ventura or snonona something i think. yeah

Thanks for this! Works for me on Twitch, and that's where I need it. One great addition would be to be able to save the size and position of the black box based on the URL. Also I'd prefer if the box didn't have a shadow but whatever. I can change that with Stylus, for now.

doesn't work in most sites youtube,9anime,facebook and many other sites after trying a lot of sites i finally found that it works on a image opened in a new tab

Doesn't Work!
