Firefox 92 Review 2021

Mozilla released Firefox 92 on September 7, 2021. This is the eight major browser update in 2021.

This is the fourth update for the new Proton user-interface which was released in June 2021.

In this blog post, I cover some of the notable changes in this new browser update.

Mozilla has been consistent in releasing regular updates for the Firefox internet browser almost every single month in 2021. Though not all their updates include major changes and new features.

In fact, in this Firefox 92 browser update, there were no major changes implemented. Most of the changes were mainly related to fixes to security vulnerabilities.

In the previous Firefox 91 update, Mozilla implemented the HTTPS-First Policy to facilitate secure connections in Private Browsing mode. They have further enhanced security as highlighted below.

The only notable change I'd like to highlight was the automatic upgrade to HTTPS, using HTTPS RR) as Alt-Svc headers. This allows a server to indicate that a particular resource should be loaded, from a different server while appearing to the user that it was still loaded from the same server.

There is a web document that explains this in a little more detail, if you'd like to learn more.

A few other minor changes in this new Firefox browser update include:

  1. Full-range color levels are now supported for video playback on many systems.
  2. An open alert in a tab no longer causes performance issues in other tabs using the same process.
  3. Certificate error pages have been redesigned for a better user experience.

Finally, Mozilla continues work on restructuring Firefox’s JavaScript memory management to be more performant and use less memory.

So these were some of the notable changes in Firefox 92. You can check the list of detailed changes in the Release Notes, you’ll find the links below. In terms of the Browsermark Benchmark test results, the overall performance of Firefox remained steady compared to the earlier version. On the other hand, Google Chrome continues to outperform overall.

Well, that's it for now. Like I said, there was really not much in this update. If you have any questions, please leave them in the comments section. Thanks for stopping by!
