Firefox for Mac OS X 10.11.2 won't upload files to remote websites since 43.0.1 update
Since tonight's 43.0.1 update, Firefox will no longer upload files to remote websites. I've tried photos to Facebook, data files to remote data processing sites and all time out or return "connection reset by host" error messages. Safari still works fine, so it's not the remote sites. Firefox also refuses to quit or force quit and even stops the OS from restarting. Anyone else having these problems on Mac OS 10.11.2 (El Capitan)

What is the install version and OS of the desktop that you are remoting to?
What security software do you have?
Did you check whether your Anti-Virus software isn't blocking the upload or tries to scan the and takes to long?
You could try to upload the same file a second time in case your security software lets the file pass quicker.
