Hell hath no fury like a Bieber fan scorned! A man has angered millions of Justin Bieber fans by creating a web add-on to combat the overwhelming internet attention on the teenage singing sensation.

Greg Leuch told Canada's QMI Agency that he created the add-on for web browser Mozilla Firefox called 'Shaved Bieber' with the help of Free Art and Technology Lab after reading complaints about 'Bieber fever' online and after receiving pleas from his friends to do something about it.

One particular plea to Leuch said, "Dude, you have to do something so I can quit seeing Justin Bieber online," and within six hours, he finished the task.

Since posting the add-on online roughly two weeks ago, Leuch has been receiving death threats from the Canadian singer's teenage fans. One 15-year-old Swiss girl even likened Leuch to Hitler because "what you're doing is going back to World War II all over again. Hitler wanting to erase Jews from society -- you want to erase Justin Bieber..."

Some have reached out to Leuch via his Twitter account where one angry fan posted: "YOU'RE DEAD!! DIE! DIE! DIE! DIE! DELETE YOUR ****ING CREATION!!" and "I'll sue you!!!!!! Dont (sic) mess on Bieber! your (sic) creation is stupid!!"

On the other hand, some fans have had the add-on installed by their parents to minimise the frenzy where one fan tweeted, "Mum put that shaved bieber thing on all our computers! I'm like crying, I hate u sooo much mum."

Leuch has taken things in stride by even setting up a tumblr account to post interesting reactions towards his creation, be it good or bad.

Currently, he is said to be working on a similar application to block other celebrities like Lady Gaga, Paris Hilton, and Britney Spears.
