Now you can roll back to a previous version of your extension

4 responses

Firefox logoIn response to feedback we’ve heard from the community, AMO (addons.mozilla.org) just introduced a new feature allowing developers the ability to quickly roll back to a previously approved extension version. The most common need for roll-back ability are occasions when developers may release a new version they later discover has critical bugs. Now in such cases, instead of needing to make fast fixes and quickly submit an even newer version, which could be further delayed during a review process, developers are free to revert back to a previously approved version.

For users who may have already installed the buggy version that’s later pulled, the extension will update to the roll-back version when Firefox checks for the next update (which occurs every 24 hours by default, save for users who’ve turned off automatic updates from the Add-ons Manager).

    This is excellent news, Scott. The introduction of an instant rollback feature is a huge win for stability—it’s much better for the user experience than a broken extension sitting in the wild for the duration of a new review cycle. Peace of mind for the developer is a great secondary benefit!

    On a related note to discovering critical bugs and performance: I put together a resource that might be useful for developers looking to optimize before a release. It’s a tool that helps identify bottlenecks in code execution, which often lead to the kind of slowdowns that force those emergency updates.

    If any other developers are interested in a proactive performance check, you can find the tool here: https://bottleneckcalculator.tech/

    Thanks to the AMO team for continuing to improve the developer experience!

    So let’s set ask the question is every little thing really helping or damaging the apps ability to read ,detect ,and save life from death. A better question is where is the emergency exit and are we consumers with guilty conscience or flat out practicing malicious acts with deceit and bad character takeaways that don’t give a thought to consequences. Good day

    This new rollback feature is such a relief. I’ve had extensions crash after updates, and being able to revert quickly is a lifesaver.

    By the way, I’ve been experimenting with how web tools present user data — like how my Starbucks Calorie Calculator visualizes nutrition changes. It’s interesting how version control and data presentation overlap in usability.

    Really appreciate this update, Mozilla team!
