Mozilla is changing Firefox’s release schedule from September, with new stable versions planned every two weeks instead of once a month.
This shift toward a quicker release cycle marks a significant change for Mozilla and its flagship browser, Firefox. Instead of the traditional monthly updates, users will now see updates arriving every two weeks. Mozilla believes that a faster release cadence makes the schedule more predictable, enabling features and improvements that are ready to ship to be rolled out more swiftly.
OMG! Ubuntu Firefox Add-on
In a message directed at developers, Mozilla describes this new schedule as an experiment they plan to closely monitor. The aim is to ensure that the increased frequency of updates has a positive impact. If necessary, adjustments will be made to the speed of releases based on their findings.
The last stable version to be released under the current monthly schedule will be Firefox 154, set for launch on August 18. Following this, Firefox 155 is planned for September 1, marking the start of the new two-week release rhythm.
Interestingly, despite the accelerated release pace, Mozilla’s engineers will not be pressured to work faster. Features that aren’t ready will remain in development until they meet quality standards. This ensures that faster releases do not compromise the overall quality of the browser.
Introducing a bi-weekly release schedule could help Firefox compete more effectively with its many Chromium-based rivals, such as Google Chrome, which already embraces a similar update cycle. Frequent updates can make a browser feel more alive and responsive to user needs.
The real question, however, is whether this strategy will convert more users to Firefox. While current users receive maintenance updates regularly, which keeps them accustomed to frequent changes, it’s still uncertain if this momentum will sway users from rival browsers to choose Firefox. Only time will tell if a faster release strategy translates to an expanded user base.
Nothing for Users to Do, Though
For existing Firefox users, there’s nothing extra to do in terms of tracking the new update schedule. Updates will continue to roll out through the same channels as before. For users on Windows and macOS, this will happen via the browser’s built-in update system, while Ubuntu users will receive updates through Snap or Mozilla’s APT repo.
For those who prefer a more stable experience without the constant churn of updates, the Firefox Extended Support Release (ESR) channel will continue to offer a slower pace. This version of Firefox will have longer gaps between major releases that include significant new features or major design changes. Importantly, the ESR version still receives regular security updates, ensuring that users remain protected without sacrificing stability.
As mentioned earlier, Mozilla is not committing to maintaining this two-week release cycle indefinitely. The company plans to monitor the outcomes of this experimental approach closely, making changes if necessary. Thus, the future of Firefox’s release schedule remains fluid, which adds an element of intrigue to this development in the open-source browser space.
Does moving to a faster release schedule make sense for Mozilla, or is a slower, steady approach a better fit? Let me know what you think.
