Rated 5 out of 5 stars

Even after disabling, then uninstalling the extension, I can't get the song out of my head.
I want my money back!

Rated 5 out of 5 stars

Installed it on a coworkers computer, gives the whole office a laugh everytime it sets off (every 5-20 minutes)

This user has a previous review of this add-on.

A lot of fun!! Rated 5 out of 5 stars

Installed Trololololo Man in all the family's profiles. Drove them crazy for 2 weeks. They were all positive we had some kind of malware on the main desktop that somehow infected their laptops.

BEWARE!! They may come after you and get even!

Thanks Frank!!

A light-hearted extension, that makes me laugh, sometimes when I really could use it. I installed it on my wife's Firefox, and now she thinks her computer is haunted. :p
It's great fun. Thanks for this.
