What does facebook chat use when you pop it out? I was using it to chat with a friend last night and my system slowed to a crawl. Firefox's CPU usage showed something like 120%.
I would get done typing a short sentence and have to wait for 30-40 seconds as each letter slowly appeared. I'm wondering if it's flash based or something else. I didn't try it in another browser to see if it was just Firefox.
I can safely call Facebook a resource hog without looking over my shoulder. It blows. Now Facebook lite won't let you read your inbox messages - gets a Facebook fail whale
