Firefox Apk Android 4.2.2 May 2026

Running modern Firefox on an Android 4.2.2 (Jelly Bean) device is a challenge since current versions of the browser typically require Android 8.0 or later. To get Firefox running on such an old operating system, you must use legacy APKs from several years ago. The Best Version for Android 4.2.2

Because these versions are no longer on the Google Play Store for older devices, you must use reputable third-party repositories:

Using a legacy browser on an old OS comes with significant risks:

No Extensions: While modern Firefox supports limited extensions, many current add-ons will not be compatible with these older "Fennec" based versions.
