Works very good!

actually works better than youtube HD extensions. you can see the results right away when you make changes is a great option.

This developer loves to sneak in intrusive ads into your YouTube experience. Really disgusting practice

This addon included invasive promotion of another addon on youtube, the addon it suggests you install alters youtube results in a very intrusive way, declared as spam.

Injecting ads into webpages is a big no.

advertises his other addons on yt page

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.

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.
