Hello,

I downloaded the Firefox installer from the official website (https://www.mozilla.org/ru/firefox/download/thanks/). After downloading, I checked the SHA256 hash of the file: 051deb55cf9579e1f9b3bad71ec4a390353c568ef21849671953d08343b4e890.

However, this hash does not match any of the hashes listed on the official page: https://ftp.mozilla.org/pub/firefox/releases/133.0.3/SHA256SUMS.

Additionally, a VirusTotal scan flagged the file with a potential virus alert.

Could you clarify why there might be a discrepancy in the hash and whether this file could be legitimate?

Thank you.
