Frequently Asked Questions

How do I increase YouTube speed to more than 2x?

Native YouTube controls limit playback speed to 2.0x in fixed 0.25x steps. This extension allows you to bypass that limit and set exact decimal speeds up to 4.0x (such as 2.2x, 2.5x, or 3.25x) using custom hotkeys, on-screen preset buttons, or mousewheel scrolling.

Does this Custom Speed Controller for YouTube work on AZERTY keyboards

Yes. Standard YouTube hotkeys often break on non-English layouts due to Shift and Caps Lock keycode conflicts. Because our shortcut engine lets you bind custom hotkeys to match your exact physical key positions, you can easily set up hotkeys that work reliably on AZERTY, QWERTY, and other international layouts.

Will my video speed reset when opening new tabs or skipping ahead?

No. The extension maintains your active speed through skips, buffering, and quality changes, and automatically applies your saved channel presets as new videos load so you rarely have to adjust speed manually.

How does per-channel default speed saving work?

You can configure specific playback speeds for individual creators. Fast-talking channels can automatically play at slower speeds, while slow tutorials auto-play faster. You can save defaults for up to 3 channels on the free tier, or unlock unlimited channels with a Pro license.

Is my viewing history or browser data tracked?

No. Core playback features run locally inside your browser with zero activity logging, search tracking, or remote server data collection. Network access is strictly limited to managing optional Pro licenses.
