How do I get rid of these Facebook advertisements?

[distinct]

I never had ads like these before but now they suddenly appear:

I blame my sister for always screwing around on random sites ~_~

Thanks.

As I use Google Chrome, I have no idea if the web browser affects how you see advertisements!

For Firefox you can use a very useful an add-on called Adblock Plus. However, should you ever switch to Google Chrome, I would recommend the extension AdBlock, which not only removes all ads from Facebook but ads on other sites as well.
