I do leave it disabled 99% of the time, but when you need it you neeeed it. Don't take your annual training without it.

Идеально просто, то что во многих браузерах просто нет.

Great extension, thank you! I have one question: how can I scale video Y and X simultaneously with shortcut? Also, aspect lock doesn't work when adding a slider to the page. And one feature request, would it be possible to put current speed, for example in the circle widget?

Не работает совсем

this addon is simple but really useful. it lets me control video speed, rewind, fast-forward, and adjust volume with shortcuts. works great across different websites and is easy to customize.

Excelente! Funciona em qq site....

One of the best Firefox extensions.

The best one imo, I probably tryed them all. Was already using it on chrome since ages, never disappointed.

Не работает совсем

Recently, I suddenly found that when using this plugin together with Vimium, there will be a problem where the shortcut keys stop working. Even if the keys that cause shortcut key conflicts have been avoided, there will still be issues where the shortcut keys cannot be used.

What can I say? It does everything you could ever want it to do and more. All keybinds can be freely configured, and you can easily tell it to ignore a domain if you prefer the native controls anyway.

The only thing this addon needs is mouse shortcuts, like scroll wheel for volume.

Other than that, a perfect addon

Just WOW, AWESOME. Workflow is now more efficient than ever before.
My example of priority settings, only.
PAGE SHORTCUTS.
- Allowlist (“URL conditions” switched from Blocklist to Allowlist.)
- Modify keys. Same/similar to YT, odysee, rumble, bitchute, etc. AND to avoid any conflicts with Vimium by Phil Crosby (FF ext)
URL RULES
- AutoPlay (Run Code to force AutoPlay on selected media platforms with no native support)
- Top Quality Video (Run Code on selected media platforms to always select top quality)
- ON for Allowlist (selected media platforms)
- OFF Global (To avoid any conflict with Vimium for non media platforms)
OPTIONS
- Show indicator > Customize. To match for consistency with Custom OSD by x10shun (GNOME ext)

I wish it had documentation wiki (Unless I missed it). No problem for me. Used search in GitHub and Google AI Mode for creating “Run Code” in URL Rules. Used FF Dev Tools to “pick element” to copy Inner and Outer HTML to give AI context for giving correct code for AutoPlay and Top Quality Video.

I like the Global Speed intuitive settings page, UX & UI.

Ubuntu 24.04.4 LTS
Firefox 149.0

I had a perfect experience using this extension on Edge. However, after switching to Firefox, I encountered an issue: after playing at an accelerated speed for a while, resetting the speed back to 1x sometimes causes audio-video desynchronization. Please note that this issue is intermittent and does not happen every time.

Fantastic add-on. Easy to use and easy to switch back to what speeds I want. Godsend for people like me who like to watch youtube on 1.5-2.5 speed. Absolute must if you have a job that has elearning videos that take forever to go through. 5/5 stars from me
