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):

SHA256 caceeacec49a4d4cac94bb48266adb28bc53515345619e336c26488846717a56

SHA512 0c1ffcd219c0c788ac01064bfbb800a95990111539e7ed20c7e9b279c7502e59cef1c7b0274f57cba71bd3bf2493d579b9f7157346ad9a0821913ecba6558e02

they do not match any from https://releases.mozilla.org/pub/firefox/releases/79.0/SHA256SUMS and https://releases.mozilla.org/pub/firefox/releases/79.0/SHA512SUMS

When I downloaded the same installer on Windows via Firefox checksums were different than before (calculated by the same command)

SHA256 bc4dd6ce1b53b194bc95ef908278f670494dd5fb782eea2da563098e58a2db3d

SHA512 ecec87468644b2219618e21e127d54460222346fb639a11bdd31685ffcd9ce56219991a64e4144f2f80a8f88672dbad3ab4f0edda388c11c4d9bcd8446e16a8c

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?

Thanks
