are you sure the browser is allowed to write on facebook ? rechecking your settings or reloading the page might help . hope it does help.
Make sure you are not blocking content.
Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}
