Hi The best place to download and get updates from is the Google Play store.

''<p>dragonzhao [[#question-1293483|said]]</p>'' <blockquote> Do firefox have mirror to download the latest Firefox Nightly for Developers APK file directly? </blockquote> I gave you two options of where to get Firefox for Android from Mozilla in your other thread. [/questions/1293461] and one place is where you can get the Fennec Beta and Nightly. https://www.mozilla.org/firefox/all/#product-android-release where you can change the drop down to '''Firefox Android Beta''' and '''Firefox Android Nightly'''. Another link is https://www.mozilla.org/firefox/android/all/ which leads to same place.

unfortunately the direct apk downloads are outdated, latest version still is 68.11.0 please upload new firefox for direct download :)
