Mozilla's support team has made the dramatic but justified decision to block all versions of Flash Player from Firefox until Adobe releases a patch.

The block, announced by head of Firefox support Mark Schmidt, comes in response to the recent discovery of two critical zero-day flaws in Flash Player.

To clarify the matter, Schmidt later added: "Flash is only blocked until Adobe releases a version which isn't being actively exploited by publicly known vulnerabilities."

Adobe has promised patches for the two flaws, but the patches are yet to arrive. Security experts fear that hackers are already working to integrate attacks for the bug into exploit kits, which has already happened for one of the two new flaws.
