Facebook pops up

Hey, do you have the same problem as when you tend to reply a post and after you click the submit button, the facebook pops up to ask you to share that post on your facebook? This often happens to me. I have to click cancel again and again. Is there any way to stop this? 

You can disable the Facebook Connect feature to stop it. I had the same problem, and it was annoying. The instructions are here under "Can I disconnect later if I want to?":

Thank you jcat. It has been fixed now. But, another problem shows up that some adchoices ads show up on my Yahoo email and some websites which i don't really remember. Do you have any ideas about what adchoices is? I have googled and found out that some posts for example this page say that is is a malware!!! Still get frustrated about it. Wait for your reply.

I can't say I have any experience with that one. Do you have Malwarebytes installed on your computer? There's a free version, and it usually takes care of things like that.
