Mozilla has changed the original end of support deadline for Firefox on Windows 7 and Windows 8 devices. The organization’s original plan was to end support in September 2024.
This coincided with the release of the next Firefox ESR base and would allow Mozilla to unload legacy code from Firefox.
Byron Jourdan, Mozilla’s Senior Director of Product Management, confirmed on Reddit that support will be extended.
He wrote:
We’re planning to extend support for Windows 7 users past the currently planned date and give them better options for migrating to a new PC when they choose to.
The confirmation was posted during an Ask Me Anything (AMA) session of Mozilla’s leadership team on Reddit in June (spotted by Sören Hentzschel)
Jourdan does not provide specifics on the extension, only that support will be extended for as long as usage numbers are still high.
About 10% of Firefox users are still using Windows 7 or Windows 8 / 8.1 at the time of writing. That is significant enough for Mozilla to extend support.
Firefox users who run the browser on Windows 7 or 8 devices were moved to Firefox 115 ESR some time ago. This is the Extended Support Release, which offers better stability as new features are only introduced when the ESR-base changes.
This happens when Firefox 128 is going to be released on July 9, 2024. The previous ESR, 115 in this case, continues to be maintained for a bit longer.
Mozilla planned to drop support for it on September 3, 2024 with the release of Firefox 115.15.
While the official release schedule has not been updated yet, it seems likely that Mozilla will extend the end of Firefox 115 ESR.
Chromium-based browsers like Google Chrome or Microsoft Edge are no longer supporting the old Windows versions.
Closing Words
Firefox users on Windows 7 or 8 will continue to receive security updates for the foreseeable future. Mozilla has yet to update the official support pages to reflect the change.
Do you use Firefox? Are you affected by the change?
