Glitch this από cubeleco

Toggle glitching via the keyboard shortcut or the popup panel. The speed, amount, and types of glitching can be controlled in the popup panel. Works best and fastest on smaller pages (1-2 screen lengths).

Glitching is only applied when the current page has focus. So if the popup panel is open or another tab is focused: the glitching will be paused or started on the focused tab respectively.
