Periodically completely kills performance on websites that don't even have a video in them. At least there's a blacklist feature.

I like it, but it breaks reddit

Doesn't work in Firefox Picture-in-Picture player.

It works, but it's outdated. Outdated JavaScript + access to all websites = disaster. Moving to an active fork.

Good functionality, helpful and customizable shortcuts, very unobtrusive design.
However, it is prone to crashes when skipping backwards in sped up videos and would often appear to slow down pages with no videos at all. I also had the impression that turning the speed up and down didn't entirely cancel out

I've been using this extension for some time now, but it seems like it was blocking PayPal - couldn't sign in to the website. When I disabled this add-on all went normal with PayPal. I've read that there's a risk involved with extensions like this one that request "Access your data for all websites" - because they can read usernames and passwords. Since this add-on is not monitored nor updated I decided to remove it.

3 stars only because of security issues!!!

The blacklist it has now is NOT the way to go! There should be a white list to enabled the extension only on the most common video sites.

Access your data for all websites 👎

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.

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.

This extension is excellent. The keyboard shortcuts (which are customizable) are all you need to control it. Speed can be set to what you want and a hotkey can be used to go to a preset speed that you likely use all the time.

However, there is no privacy policy and the extension has the status of 'Access your data for all websites'. This means it can access every on your browser including usernames and password.

Another user has brought issue up; it can be found on GitHub by clicking the 'support URL' on the extensions main page, clicking on 'issues' and then searching for "data". The dev did come back to the user and point that although the extension has "root" access to the browser no information is passed out externally.

All we can can do it take his word for it. A would recommend this information be put into a proper privacy policy which can then be found easier for other user with the same concerns. I'll be looking to find a similar extension that takes privacy a little bit more seriously in the meantime.

It does the job, but whenever I pause/skip the video the speed is reverted back to 1.00 (on some websites)

Hi, I added this extention to use on my android phone, but it isnt designed for mobile use is it? Can you advise?
Thanks

Strange choice of adding websites to exceptions by default. I only installed it to control playback speed on twitter. If I was any less careful, I would've thought the extension doesn't work.

Audio is not good when u go for 2x and above.Please work on audio (android add-on)

some video servers like rapidvideo doesn't load the plugin, then it cannot control its playrate

Dobrý

I liked that it worked by keyboard but I dont want that icon on the video all the time. Also it disorts the sound too much by slowing or speeding it up (which is prolly a yt thing because the same disortion happens when I use the yt speed settings). When I can use my software player with slow or fast vids and change the speed there than the sound is perfect.

The speed drops down to 1.00 when you enter and exit full-screen mode.

Very usefull addon, but I'm having a issue. IDK why but this addon is making it impossible to load some sites. And it happens only at Firefox, e.g. for acess this site: https://www.noalvo.com/ I have to disable the addon, If I turn it on, the site dosen't load... I'm also thinking that the addon is responsable to use a lot of ram memory

I do not like using keyboard. I like my mouse. Also, put the controls together with the YouTube's controls. I mean, add x3 to YouTube's standard set of buttons. i do not like any additional icons in my browser. Just mix your soft with YouTube's GUI in the browser window.

ok so i love this add-on... on chrome. the audio quality starts glitching out on anything over 2.00 speed on firefox. i usually watch youtube videos at 2.50+ but i can't deal with the robotic sound on firefox. however i really do prefer firefox and would rather switch over to firefox, but this video speed issue is the only thing stopping me. not sure if it's an add-on problem or just a firefox issue that can't be helped.
