Mozilla Launches Firefox 93 – Support for Thrifty AVIF Images and Notable Privacy and Security Improvements

Mozilla has updated its Firefox browser to version 93. The latest update contains quite a few new features that should improve browser performance and security. One of the changes in this update is support for AVIF images, which provides significant bandwidth savings over existing image formats.

On the security front, Firefox 93 now automatically tries to prevent downloading files from unsecured HTTP addresses. Mozilla regards such downloads as a serious security risk that could allow an attacker to compromise the user’s system. When attempting to download a file from an unsafe location, the user will be warned of the risk and will be prompted to delete the file, although they will also be given the option to allow the download.

As for privacy, Firefox 23 comes with SmartBlock 3.0, which attempts to block third-party trackers that track user activity on the Internet, while trying not to disrupt the web pages. In addition, users of Windows computers with a critically small amount of RAM will have access to the function of unloading tabs. The browser will unload them from memory based on the time of the last access. Mozilla claims that this method will reduce the number of Firefox crashes due to insufficient RAM.

Other improvements include form filling support in Firefox’s built-in PDF viewer. In addition, macOS users will be prompted to complete the installation if they launch the browser from a mounted .dmg image to prevent data loss. This message will only be displayed the first time it is launched, so as not to annoy users who intentionally use Firefox this way.

Users who are already using the Mozilla browser will receive the update automatically. Everyone else can download it from the official Firefox website.

If you noticed an error – select it with the mouse and press CTRL + ENTER.
