Puts ads on your youtube page for his other addons. Don't recommend.

Inserting advertisements for other extensions by inserting elements into a webpage is not OK. I would recommend switching to other extensions as this is very shady at best.

Inserts ads for their other addons without origin or context as a random box on the youtube page, making you consider if you have adware installed. That's unacceptable.

I just recently started using avi12 and I think it is really Awesome! I would recommend you try it out. I think you will enjoy it asc

Seriously? Adding advertisements in an add-on without my consent?

Not cool. Not cool at all. Uninstalled. Take your advertisements and shove them.

Not to mention deleting the GitHub issue that reports this? That's not shady at all.

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.
