He intentado esto que encontre pero no funciona.
Solution:
A workaround has been provided on the Mozilla Firefox Support Site. This works for Firefox 39 and above.
Open Mozilla FireFox
In FireFox, type about:config into the address bar and press enter
Accept the This might void your warranty! warning
In the search field at the top of the screen, enter security.ssl3.dhe_rsa_aes
Double-click each result (128 and 256) to toggle the value to False
Access WebFiles, as it should be possible to connect successfully
Note:
Remember to change the values that were modified back to their default state when done.
