A message now appears saying that Flash — the plug-in that enables animation, browser games and other graphics online — is vulnerable, along with a message that Mozilla reserves the right to block software that “seriously compromises Firefox security.”
The ban is temporary — it will stay in place as long as there’s a version of Flash with publicly known security problems, Mozilla said. (Adobe is working on a fix.) If users really want to run Flash to view videos or use other Flash-based Web tools, they can do so — as long as they read a security warning from Mozilla first. But Mozilla is also advocating for a general end to using Flash as a Web standard.
First Facebook, now Mozilla — the writing is on the wall.
