Play Faster and un💩ify videos od janspambox

Each time you click the addon's icon in the tool bar, it finds all playing video and audio elements and sets their playback speed, cycling through different speeds on each click.

The "un💩ify playing videos" feature available in the extension's context menu (right-click the icon) tries to remove bad/user-hostile user interfaces and let you use the normal video controls, including fullscreen. Some web sites will continue to block the video's context menu; you can still access it using shift+rightclick on the video.

The "un💩ify" feature uses only some generic tricks and no site-specific code, so it won't work everywhere and it will likely completely break on some web sites. (On a technical level, it finds all playing video elements, enables controls, applies a z-index and positioning, and tries to block some event listeners.)

No data collection, and the addon is only active when you click it.
