Facebook Dislike Button--I Like It!

It's not an official Facebook Dislike button, It ISN'T the Facebook Dislike button scam either. But it is legit and I Like it (see what I did there? ^^,)

For now the Facebook Dislike button works only on Firefox as an add-on. As you would expect, the the Firefox Facebook Dislike button add-on adds a Dislike option alongside the Like button.
Now, when a friend says:

 you can show your support by "Disliking" it (or would you prefer to "Like" it? ^^,)

The only problem with the Firefox add-on is that only those who have installed the Firefox Facebook Dislike button add-on can see the results. If you want it, you can download the Firefox Facebook Dislike button add-on HERE.

Do you "Like" the Dislike button? Do you think Facebook should get the hint and add the Dislike Button officially?
