2026 update: plugin now requires permissions to view browsing history

The developer uses this extension as a personal facebook wall. This extension has nagged me one too many times with completely unrelated messaging. First was the data harvesting, and now begging for donations because the developer lives near a war zone. Don't use this extension if you value your time, or are frustrated by ads. There is probably some unsavory data harvesting going on in the background as well.

Sometimes buggy on Android: settings for the video pops up briefly at the start of playback before automatically disappearing. Also sometimes screws up when opening video from my YouTube history - redirects to my YouTube subscriptions instead of the video page I wanted to load (Firefox Nightly for Android). Edit: Still this addon is very useful on Android, as it is the only working one that lets one set YouTube playback quality. Please kindly allow this again to be installed on Android. Edit 2: seems to have gotten worse on Android and m.youtube.com, pops up the video settings every time I make the video time jump to another point, and also sometimes even seems to trigger a redirect to a different video.

Good Extension

it does what it says, but there's a really annoying "support YTHD" button next to the subscribe button/channel name that cuts off the channel name most of the time.

avi12, you need to have a 3rd party audit your scripts or you will keep losing users.

Insta-remove, required access to history and all webpages. You(avi12) should not be selling user data!

I love and so appreciate this extension! As someone with limited expensive bandwidth this saves me so much grief. Have been using it for a long time, but for some reason, it stopped working on my MacBook Pro. Still works great on my iMac. Please help!

New version wants permissions no extension should ever be asking for, i.e. browsing history. After already being informed via an invasive Google Form that the developer is considering selling our data, I will no longer trust this extension. Vile stuff.
