Adobe's Flash software is now blocked by default on all versions of the Firefox web browser.
Mozilla, which develops Firefox, imposed the block because recently unearthed bugs in Flash were being actively used by cyber-thieves.
The bugs were detailed in a cache of documents stolen from security firm Hacking Team that was hit by attackers last week.
Adobe said it took Flash's security "seriously" and was planning bug fixes.
Flash is widely used on many websites for both multimedia and interactive elements
Seems quite a few websites (mainly gaming ones like IGN) still require Flashplayer to watch videos and probably the biggest website of them all - Facebook - requires it to watch videos on the main website (mobile version doesnt)
So as more and more security experts are calling for Flash to be killed off, is it possible at the moment?
