https://www.mozilla.org/en-US/firefox/android/all/ lists the Android apk links to be at: https://ftp.mozilla.org/pub/mozilla.org/mobile/releases/latest/android-api-9/ https://ftp.mozilla.org/pub/mozilla.org/mobile/releases/latest/android-api-11/ https://ftp.mozilla.org/pub/mozilla.org/mobile/releases/latest/android-x86/ which now redirect to 404s.
Hmm, the latest symlink is gone from https://ftp.mozilla.org/pub/mobile/releases/
I cleaned these up as part of bug 1223019, not realising that we were using that location at all. Do we get many hits on https://www.mozilla.org/en-US/firefox/android/all/ ? It's somewhat unfortunate that bouncer is not set up for this, and we're doing something different to desktop here.
I had needed to download the Firefox .apk for an old phone without Google Play store access.
Kohei, do we have the mobile version in product-details so that we can point to https://ftp.mozilla.org/pub/mozilla.org/mobile/releases/42.0.1/android-api-9/ instead ? Maybe product-details/json/mobile_details.json ?
I've copied 42.0.1 into mobile/latest/ so that the page works again. Apparently non-Google Play installs are a significant number of users.
