I needed to reinstall Firefox on this computer, so I started up Chrome to download the latest version and it blocked the download as unsafe! I had to manually tell it to download anyway.
Fuck Chrome. I'm glad I only used it to download one file and went back to Firefox.
I don't know why you're getting downvoted; out of curiosity I just now tried it on Windows myself (Google Chrome 120.0.6099.130 Official Build 64-bit) by typing mozilla.org, clicking "Firefox downloads" at the top, and selecting the one for Windows. It sailed through almost instantly.
BUT - just because it worked for me personally on a completely different machine, OS, and installer doesn't mean OP is misrepresenting what happened to him; competitive app blocking has certainly happened with Edge. For all we know it's some Google A/B trial bullshit, no telling at this point.
