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
Global Speed (v3.2.66 on AMO / v3.3.13 on GitHub)

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

Lightweight and all the elegant customization you would want and need from a straightforward app like this. Does a task that other add-ons try to do but does it better. No problems yet as of this review but the dev looks super responsive if any issues come up. A shining example of what a firefox addon should strive to be.

On Android it requires closing settings to have an effect

it had a feature where if you briefly hold and release the right click button youtube videos would stay playing in 2x and doing the same will bring the speed back down to 1x it does not work anymore

edit- hi developer before when right mouse button was clicked briefly and release it video stayed in 2x now it is not working such
edit 2- ok thank your for such a quick response please add back the bug :)

Excellent addition.
Could you let me know if there's a way to keep the speed status always displayed and not fade?

The best speed control extension! And it's open source 😎

Be careful.... All I wanted was to Draw on the page (which it seems to do well) , but I didn't realize it would control the volume on Youtube, online radio-Listen Live. First slower than I wanted, then faster. . Confused me greatly. Maybe I should have figured it out faster but it wasted an hour or two of my time, and could have wasted much more. I didn't appreciate what "Apply a default speed for all video and audio." really meant. Didn't realize "compatible" meant it would do so to everything without asking me for each source. Why would anyone want all sources to be either slowed or speeded up? More details following that line would be very helpful.

Thanks, Poly, for your speedy reply below. I will do what you say I was even able to upgrade the review from 4 stars to 5.

Amazing! It works on most places and are very customizable. Highly recommended! 🌟

Works for everything, including adds. It recently stopped working, a re-install fixed that.

Works wonders with edgenuity. would rate higher if possible

works great

in love with this addon!
