Don't hesitate to install it; all the source code is available at the link—you can check it or build it yourself. The source code is also available after installing the add-on, allowing you to verify it completely. TL;DR -- faster playback translates to better engagement and retention. The average adult reads at 250-300 words per minute (wpm). Speech averages ~150 wpm; slide presentations often closer to 100 wpm. Given the choice, most viewers speed up playback to ~1.3-1.5x to close the gap. Accelerated viewing keeps attention longer -- faster delivery means higher engagement. With practice, many settle at 2x or above and find it uncomfortable to return to 1x. HTML5 media elements expose a native playback rate API, but most players hide or artificially limit it. Speed adjustments should be effortless and frequent: we don't read at a fixed pace, and we shouldn't watch at one either. Features Universal - works on any site with HTML5 media: YouTube, Netflix, Coursera, podcasts, local files, etc. Video and audio - controls both <video> and <audio> elements. Fine-grained speed - 0.07x to 16x in configurable increments. Per-site speed rules - set a default playback speed for specific domains (e.g., always 2x on lecture sites). Per-site disable - turn off the controller on sites where you don't want it. Remember speed - optionally persist your last speed across sessions and tabs. Speed fightback - automatically re-applies your chosen speed when a site's player tries to reset it. Draggable overlay - reposition the on-video speed indicator anywhere you like. Fully customizable shortcuts - remap every key, add modifier combos (Ctrl, Shift, Alt), create multiple preferred-speed toggles. Custom controller CSS - style or reposition the overlay with your own CSS rules. Default keyboard shortcuts S - decrease playback speed D - increase playback speed R - reset playback speed to 1.0x Z - rewind video by 10 seconds X - advance video by 10 seconds G - toggle between current and preferred speed V - show/hide the controller M - set a marker at current position J - jump back to the previously set marker All shortcuts are fully customizable in the extension's settings page. You can reassign keys, add modifier combinations, and define multiple preferred-speed shortcuts with different values for quick toggling. Click Add New in settings to create additional bindings. Refresh the page after making changes for them to take effect. ## Rankings - #34,991 — Overall - #50 — video speed - #100 — hesitate - #197 — speed - #227 — self control ## Permissions and access ### Permissions - `storage` - `tabs` - `activeTab` - `declarativeNetRequest` ### Host permissions - `http://*/*` - `https://*/*` ### Content script matches - `*` - `` ## Safety - **Risk impact:** High risk impact - **Risk likelihood:** High risk likelihood ### Analysis details - Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern. - This extension has low user count.
