Mozilla, the company behind the popular Firefox browser, announced several new security measures that have been implemented, and some that will be soon implemented into Firefox.
Firefox has had security mechanisms that check every site that you visit against malware databases for a while now. If the site is on a black-list, you will be warned before the site even loads, to protect you from any malicious injections or downloads that could reside on the site. From now on, Windows’ version of Firefox is even checking the files that you download to make sure they are not infected and prevent malware from touching your system.
Starting from the next Firefox version which is to be released this September, even more security mechanisms will be working on the browser. Firefox will check downloaded file’s signature and compare it against the database. If the signature is blacklisted, the file will be automatically removed. Cyber criminals usually sign files with fake signatures or don’t sign them at all. With files, that are not in whitelist or in blacklist, Firefox will use Google’s Safe Browsing service, which will determine whether the file is infected by using file’s metadata, in other words, a unique fingerprint to match it against the database of files. Google’s acquisition of VirusTotal.com service, which scans a given file with tens of different anti-viruses, will improve Firefox’s ability to determine whether the file is really good or really bad.
These security settings will be enabled by default and, of course, can be disabled (although not recommended). If you are using an old version of Firefox, or a different browser, now is a good time to switch or update. Download Firefox to keep your PC safer.
