Following widespread reports of serious security issues with Adobe Flash, Mozilla has decided to block the Flash Player add-on in their Firefox web browser by default to protect users from being infected with malware.

Adobe has been under siege over the past week after three serious Flash vulnerabilities were discovered in a 400 GB dump of 'security' firm Hacking Team's internal documentation. Hacking Team's data included instructions on how to exploit the vulnerabilities, which led to cases of "immediate weaponization" in the wild, according to Malwarebytes.

One of the ways to prevent attackers from exploiting Flash vulnerabilities is to cut off access to Flash entirely. Mozilla has decided that this is the best course of action for Firefox, taking on the advice of security experts which suggest either uninstalling Flash Player from your system entirely, or switching to a click-to-play Flash activation method.

Adobe has already patched the serious security vulnerabilities in Flash, but it might be too late to save the company's notorious multimedia platform. Facebook's head of security has urged Adobe to kill Flash, while most mobile platforms don't even support Flash in favor of newer HTML5 multimedia standards.

Mozilla may end up re-enabling Flash Player in Firefox, but it would have to be disabled again when yet another security issue is inevitably discovered. It might annoy those who play Flash-based games or videos in their browser, but perhaps the best course of action really is to have Adobe kill off Flash once and for all.

‚ÄčUpdate: Adobe has released a patch for Flash that has addressed the vulnerabilities currently being exploited in the wild.
