For a couple months now I have not been able to paste anything on Facebook via Firefox. I can use Explorer, Chrome and can paste anywhere else just fine. When I paste on Facebook messenger, the chat window closes and I have to refresh Facebook to even be able to see my messages again. Otherwise, I click on it and nothing happens. When I try to paste a post on my wall, it I get a "Something isn't working. This may be because of a technical error we're working to fix." (I just copied and pasted that here no problem) Tried clearing history/cookies/cache. Help?
