After a number of issues and exploits have been discovered recently, Mozilla has taken a big step and is now blocking Flash in all of its Firefox browsers.
Flash, the much maligned and hated software on which a surprisingly big part of the web still relies, has often been criticized for its faulty security. More recently, unpatched vulnerabilities, which are being exploited in the wild, have transformed Adobeís platform into an even bigger liability.
But youíre a bit safer if you rely on Firefox, as Mozilla has put Flash on its blacklist of software and addons. The program is disabled by default and can only be enabled if the user clicks on a prompt that pops up. The reasoning here is that Flash neednít be blocked completely, but it shouldn't be running without the userís knowledge either.
