Run a couple sites using Joomla 3.6.2 and Civi 4.7.10 - Did the upgrade tonight - all went well. One site is having problems with CKEditor and the link tool. Edit link or adding a new link just simply doesn't work. - it shows all options (Link,Anchor and Mailto) It is fine in my other site. I can work around it by using the TinyMCE extension and changing editors. Image is a picture of trying to edit an existing link - which shows up blank. Choosing OK just copies any text you have in the link info box - does not make the link ..
