Unable to Preview Posts in Firefox

When I click on Preview, it says “You do not have permission to preview drafts.” And I am the only Admin.

I’ve also noticed under Posts, when you click on Quick Edit and then click Update. I just loads and loads and loads…forever. If you wait long enough the changes will save but it still shows that it is loading.

I’ve cleared cookies and tried it on two different computers. I was able to get it to work a few times in Internet Explorer but still had some issues.
