順著 SHA-1 正式被打穿，Mozilla 也正式宣佈從下一個版本的 Firefox 將完全關閉 SHA-1 支援 (看敘述應該還是可以透過 about:config 開)：「The end of SHA-1 on the Public Web」。
As announced last fall, we’ve been disabling SHA-1 for increasing numbers of Firefox users since the release of Firefox 51 using a gradual phase-in technique. Tomorrow, this deprecation policy will reach all Firefox users. It is enabled by default in Firefox 52.
大家都開始有動作了...
