Unable to use certain features

I just installed Easy Social a few days ago and I have run into a couple of problems, the first is not being able to log out while using the latest version of Firefox, the issue does not exist while using the latest versions of Chrome or IE. The second issue is not being able to click on things like "Add Friend", "Follow" or "Message" from a user's profile page while using Firefox or Chrome, this issue does not exist while using IE.

Any help with getting the issues resolved would be appreciated very much.
