Hi all, I dowloaded a file "firefox-57.0.1.apk" from "https://firefox.fr.uptodown.com/android/telecharger" for my Android mobile phone. After installation, got a weird message in russian (did not record it) and Firefox 57.0.1 didn't work. I uninstalled everything, but now I am trying to check the source of this apk, as it might have compromised my phone. The checksum SHA256 of this apk file is "dae3bfeabfdc7d48c9d2d240bfeea70faec15e02d3fce7be644f6b5640d7a722" Can anybody tell me if the above mentioned SHA 256 signature is from a valid Mozilla source file? Thanks a lot. Best regards. JRR
