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.
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.

It's good but the controls are showing up right in the middle of the video. Tried hiding the controls but they would come back after a few minutes. Tried moving them as well, same result. Hope they can get it fixed.

The controller still needs fixing, but this is ideal for Vim-obsessed power users.

I have a problem with this plug on NetFlix. The button is in the middle of the screen and is not active.

Works great. Saves a lot of time and hassle. Especially handy when a website blocks the native FF video speed control.
