Unable to Connect to Certain Sites, Help ASAP Please.

I am unable to connect to certain websites for no reason today. Sites that I can connect to are like msn.com, google/yahoo, and forums. But when I try Facebook or connect to a game. I get a time out. My wireless connection says it has a excellent signal...

Toshiba Laptop
Windows XP
Wireless Connection.

I was able to fix it by changing the IPV6 value in Firefox to true. Just type about:config in the url box of Firefox and find IPV6.

I'm still curious to why this happened to me though? Everything was normal until today.
