This review makes no sense - are you sure you're commenting on the right addon?

1) It deploys using exactly the same mechanism as every other Mozilla addon which means clicking on "Add to Firefox" and then clicking on another button to accept the permissions. If you're having an issue with deployment you should contact Mozilla support because this isn't the fault of this add-on.

2) How is two small bullet-pointed sentences "unnecessarily wordy"? There's also an image to show how the addon looks when you use the context menu. How isn't that helping?

3) Reduce what functions? What web-page?

4) I have no idea what this means: "A few weeks ago using Opera this process was almost "one button press" after media detail input(720/1080, audio setting."
