After Facebook, open source software developer Mozilla also blocked Adobe Flash Player in its browser Firefox. Explaining the ban as temporary, Mozilla explained the older versions of Flash player plugin have known vulnerabilities that might affect the browser performance.
Announcing the block as temporary, Mozilla CEO Mark Schmidt tweeted, "All versions of Flash are blocked from Firefox as of now."
However, he tweeted later that this block is effective till Adobe releases another update of Flash Player.

The move came immediately after an Italian security company hacking team demonstrated how an add-on can be developed using Flash Player to hack important files. Though Adobe has already announced to release the patch soon, the player has already been banned by Facebook as well.
Facebook security head Ale Stamos tweeted. "It is time for Adobe to announce the end of life date for Flash and to ask the browsers to set killbits on the same day."

Though Adobe Flash Player is immensely popular for tiny games and videos, the player received mixed reaction from several companies. Years back, Apple co-founder Steve Jobs wrote an open letter to Adobe Flash and decided not to feature it in iOS. Google's browser Chrome also intelligently detects the behaviour and pauses the player if required.
