X Video Gate

Blocks videos on X (Twitter) from accounts you don't follow. A blocked video is covered with a "Play in new tab" button. Tapping it opens just that one video on a bare page: no feed around it, nothing to scroll to next. Videos from accounts you follow play as usual, and GIFs are never blocked. Turning blocking off, or adding an account to the always-allow list, takes two confirmations with a 15-second wait between them. Everything runs on your device. The extension makes no network requests of its own and sends nothing anywhere. Source code: https://github.com/ygruns/x-video-gate
