The Mozilla project recently expanded their popular and successful (and free) Plugin Check service to support non-Mozilla browsers. So now, not only does this service, which scans your browser’s settings for outdated plugins, e.g., Adobe Flash Player, work with Firefox, but also with Opera, Google Chrome, Apple Safari, and even, to a limited extent, Microsoft Internet Explorer. Given that unpatched client software, especially operating systems, browsers, and browser plugins, remain the top cyber-security concern today, everyone should stop what they’re doing and go to Mozilla Plugin Check right now.
