why do these random pages appearing on my Facebook homepage?

Today I went on facebook but in my newsfeed I found 3-4 random pages I never "liked" before such as a tattoo parlour from HK, car dealer ship and weird singers. Did someone hack into my account??

That may be a possibility but i have noticed that facebook seems different on different browsers, for instance i love google chrome and i use it on facebook, but when i use mozilla fire fox i see all these adds and things on my facebook. So it could be your current browser, but if you feel unsafe and believe someone hacked your account go in and change your password.

I hope this helps
