Hash do not mach when Firefox is downloaded via Edge
I downloaded Firefox installer (for version 79.0) on Windows via Edge from here https://www.mozilla.org/pl/firefox/new/ Checksums of the downloaded installer are (calculated by `certutil -hashfile "Path_to_Firefox_installer" SHA256` and `certutil -hashfile "Path_to_Firefox_installer" SHA512` in Windows command line):
When I downloaded the same installer on Windows via Firefox checksums were different than before (calculated by the same command)
they match "win32/pl/Firefox Installer.exe" on "https://releases.mozilla.org/pub/firefox/releases/79.0/SHA256SUMS" and "https://releases.mozilla.org/pub/firefox/releases/79.0/SHA512SUMS".
What is strange the signatures of the files are identical. I downloaded installer two more times (with restarting computer in between, why not) and it gave me exact same hashes depending only on what browser i used for downloading them. Is it a known problem when downloading firefox via Edge? Is it known why this happens? Does this problem occur to you? Is Firefox downloaded via Edge safe to install?
