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
For Android 4.2.2, the most stable and feature-rich legacy version is Firefox 68.4.2. Release Date: January 2020. Minimum Requirements: Android 4.1 or higher.
Architecture: Most Jelly Bean devices use the armeabi-v7a architecture.
If version 68 feels too heavy for your older hardware, you can drop back further to Firefox 42.0.2, which was widely used on mid-range Jelly Bean tablets and phones. Where to Download Legacy APKs
Because these versions are no longer on the Google Play Store for older devices, you must use reputable third-party repositories:

| Problem | Solution |
|--------|----------|
| “App not installed” / “Parse error” | You downloaded the wrong architecture. Try the nodpi or armeabi-v7a version. |
| Browser crashes on some websites | Many modern websites require TLS 1.2 or newer JavaScript. Firefox 68 supports TLS 1.2 but may still crash on heavy sites. Use text-mode or request desktop site as a last resort. |
| Google.com says “browser not supported” | Change user agent: Type about:config in address bar, search for general.useragent.override, add a newer Android string (optional, advanced). |
| Play Store tries to update Firefox | Disable auto-update for Firefox in Play Store settings (if Play Store still works). |
