A very old yet effective extension. I recall that I met this extensions some 4 years ago, yet returned to use it..

A fabulous little instrument for playing a piano simply by clicking on a few keys. In comparison to other games around here - nice and simple.

Cute and to the point Rated 5 out of 5 stars

It's quite ingenious to use the number keys to play piano tunes though it is a quite basic piano. Cheers!

Pianos, organs or synthesizers are musical instruments that are fun to played on a keyboard and I like using it.

Ok, so I tested it and enjoyed it because it's very simple and brings immediate enjoyment. I'd recommend to develop more such musical tools.

Music and a keyboard? that's always fun to have and use. Additional keys would make it even better and more entertaining.

This is very good because this is very simple to use. Nothing can beat simplicity so in this sense I can recommend this add-on..

For me it is a relaxation bot intended for killing dull times such as times when I haven't got what to do at work, or when I am tired of worked..

An old app yet very cute and useful. This one just plays tunes of a simple piano and makes you smile for a couple of minutes. Generally it's a good app.

A nice little piano for playing accords using the keyboard. Helps to fight boredom quite well..

Adware.

Probably a malware Rated 1 out of 5 stars

I don't believe it. Because the author of this addon has another addon that steals passwords.

I hope Mozilla will check this addon for security issues. An advice: don't download it, only download addon that are clear with privacy.

Ein Spass für zwischendurch. Das ersetzt aber kein Klavier!

Nicht gerade ideal...

This is totally useless, you can't play any songs without some scales. It's just a sound effect addon.

Hahah, its funny, thank you for that addon!

Virus/malware beware! Rated 1 out of 5 stars

The piano is cute, my kids love it. But there is some kind of virus or malware attached to this thing it is NOT just adware, It has that too. I kept getting a "firefox needs to make an important security update." box. It was working THROUGH firefox! I tried to figure out which program was trying to update & I went in circles. I let it update & thank goodness for virus software! Norton caught it & said "NO!" not safe. I found a review on here that actually warned that this was virus stuff attached, so I removed the program I was being harassed by this update box every few minutes & I have not seen it since. Shame, my kids thought it was cute & I've had to tell them that the piano "made my computer sick." So I had to remove it. Cute idea, but stay away!
