YouTube Preview Speed Control por Vicky Kumar

This extension adds a speed control button directly to YouTube's hover previews, because sometimes curiosity deserves a fast-forward button. If YouTube allows muting and unmuting during a preview, you should be able to change the playback speed too.

Selectable playback speeds starting from 0.5x up to 2x directly from the UI.
Supports underlying speed adjustments up to 4x through script cycling.
Saves and persists your preferred preview speed across browsing sessions.
