A special version of Firefox for developers

Older versions of Firefox Developer Edition

It's not uncommon for the latest version of an app to cause problems when installed on older devices. Sometimes newer versions of apps may not work with your device due to system incompatibilities. Until the app developer has fixed the problem, try using an older version of the app. If you need a rollback of Firefox Developer Edition, check out the app's version history on Uptodown. It includes all the file versions available to download off Uptodown for that app. Download rollbacks of Firefox Developer Edition for Windows. Any version of Firefox Developer Edition distributed on Uptodown is completely virus-free and free to download at no cost.
