The new version is offered via in-browser upgrades and as a direct download from the Mozilla website.

Firefox 78 is the first release of the new Firefox ESR, Extended Support Release, version and as such, introduces major changes to systems that are upgraded from previous 68.x ESR versions.

The Android version of Firefox will also be upgraded to 78.0 as it follows the ESR release schedule until the migration to the new Android browser completes.

The next stable version of the Firefox web browser will be released on  July 28, 2020.
