Mozilla’s latest browser update, Firefox 133, is now available. We are going to show you what the main new features related to security are. We are used to seeing changes in this regard, with improvements that help enhance protection when browsing. In many cases, they are corrections to errors that have been detected in previous versions; in others, new features that they introduce into the software.
Keep in mind that it is precisely when browsing the Internet, when using programs such as Mozilla Firefox, that we are most at risk of suffering computer attacks. A cybercriminal could sneak in malware by opening a website or by exploiting a flaw in that browser. Therefore, using reliable, updated programs that also focus on protection is vital.
Firefox 133 is here
First of all, it should be mentioned that it makes some corrections to vulnerabilities considered critical, as well as others that are less dangerous. For example, it has fixed a bug registered as CVE-2024-11691, which affected the GPU drivers on Apple devices and had a high impact. Another vulnerability, also rated as high severity, is CVE-2024-11699, which in this case does affect all platforms.
Other security flaws fixed were rated low or medium severity. Some affected all platforms, while others only affected a specific operating system, such as Android, Windows or iOS. In the Mozilla website you can see the list of all those fixed vulnerabilities.
Beyond those fixes, they have also introduced improved features to detect trackers in redirects, as well as periodically purge cookies and data from those sites that use trackers. This reduces tracking and thus ensures greater privacy when browsing.
Another novelty is the adjustment of cookie expiration. Basically, it now adjusts the difference between the server time and the local time. This prevents errors in case the cookies are still valid on the server, but not in case the system time is changed.
In addition, it also includes changes in terms of privacy, with updates for developers and different bug fixes. It focuses on security, but without leaving aside user performance. This makes clear the importance of user experience for Mozilla as well.
Always update the browser
Regardless of these specific improvements that we have described, having the browser always updated is very important. This will help you correct vulnerabilities that can be exploited and that will compromise your privacy online. For example, a bug that an attacker could use to get your passwords.
Regardless of whether you use Firefox or any other browser, having the latest version is key. From RedesZone, we also recommend that you be careful with the extensions you add. Limit the number of plugins to only those you are actually going to use, as they are also a potential danger.
In short, Firefox 133 is now available and brings interesting new features in security. You can always set up a proxy in the browser, for example, to boost protection. But the most important thing of all is to make sure you have the latest version available.
