Older versions of Firefox
It's not uncommon for the latest version of an app to cause problems when installed on older smartphones. 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, 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 for Mac. Any version of Firefox distributed on Uptodown is completely virus-free and free to download at no cost.
