ITS PERFECT!!!

very nice addon, thnx

Very great for baby sensory video!

Can't imagine life without this add-on. However, for some reason it doesn't work at all on Apple Tv (tv.apple.com). Could you please look into it? Thank you.

The plugin works very good, but it has access to all websites and strangely when activated paypal signins do not work anymore, which is i find strange

I'm in love with this extension, it works
EVERY
SINGLE
TIME (much better than Enhancer for YouTube), and I'm able to use it with more than just YouTube, so honestly I can't hate this, it works beautifully so Bravo, the settings are simple and personnalised.

OpenSource on GitHub ❤️

quick find pop up when i press shortcut keys like s d z x etc in fireforx on my ubuntu desktop
please fix it

You will not believe how much time you save by this extension. I can no longer stand watching any video at normal speed anymore

Access your data for all websites 👎

Avevo bisogno di rallentare un video sportivo. Con Video Speed Controller ho risolto meravigliosamente in un minuto!
Complimenti!

When COVID started and all our lectures switched to online, there were plenty of people in my class trying to come up with all sorts of crazy solutions for getting through boring lecture videos quickly - this one extension saved us all a massive amount of time and hassle. Works great, keyboard shortcuts make it incredibly easy to use, and it's definitely been added to my list of essential extensions whenever I switch PCs in future. Excellent!

It works for facebook! 👍

Amazing add-on, works flawlessly and already saved me a ton of time. Thank you.

Easy to use, works most of the time but sometimes stops working, fixed by reinstalling the plugin then refreshing the webpage.

But dodgy sounding permissions required: it demands "Access your data for all websites" which means according to mozzila it "can read... [the] data you enter such as usernames and passwords."

I don't know if it actually does, but I uninstall it when not using it.

Great! Works well on most videos. Super useful and easy to control with keyboard keys. Thanks.
Sometimes switches between the little box top left and a larger box with text in it, but flicking faster and slower (s/d) can get it as-wanted.
The little speed box normally top left can appear in the middle of the video - not so helpful but can be dismissed with the X.
