100/100how this is calculated
Mozilla Firefox is free and open source software, built by a community of thousands from all over the world.
Getting the right Mozilla Firefox offline installer
Mozilla's download button gives you a small stub installer that fetches Firefox during setup. The full installer is published openly, just not on the page most people land on.
Firefox is unusual in a good way here: Mozilla publishes complete installers for every language and platform openly, and the ones listed on this page come straight from that release infrastructure.
Each build is language-specific. Take the en-US package unless you need a different interface language, because the language is baked into the installer rather than chosen at runtime.

Install Firefox silently
The unattended switch below is the one Mozilla declares in the installer manifest, not one we guessed by trying flags.
32-bit · machine scope · publisher-declared
.\Firefox Setup 153.0.3.exe /S /PreventRebootRequired=trueDeploying Firefox properly
Mozilla ships a real MSI and an MSIX for enterprise deployment, and they are not the file the download page gives you. The stub you get from mozilla.org is a downloader; the MSI is the one that installs unattended and predictably.
Configuration does not go on the command line. Firefox reads a policies.json file placed in a distribution folder next to the executable, and that is where you set the homepage, disable telemetry, pin extensions or turn off the update service. Deploying the MSI and then dropping policies.json in place is the whole procedure.
The switch above prevents the reboot prompt. Firefox does not need a reboot to install, but the installer will ask under some conditions and that stalls an unattended run.
Turn off automatic updates or your deployment drifts
Firefox updates itself within days, so the version you carefully deployed is not the version running next week. If you need a fixed version, set DisableAppUpdate in policies.json, and plan how you will roll updates yourself. If you do not need a fixed version, leave updates on: an out-of-date browser is a worse problem than drift.
ESR is a different package
Extended Support Release has its own installer and its own version line, and it is what most managed environments actually want. Installing regular Firefox and expecting ESR behaviour is a common and expensive mistake.
Run it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.
Download Mozilla Firefox (en-US) for Mac

Extensions Mozilla Firefox (en-US) registers itself to handle.
Is Mozilla Firefox (en-US) safe to download?
Yes, in the sense we can actually verify: the installer downloads from mozilla.net, which is a domain we have tied to Mozilla.
Every one of the 3 installers on this page comes with the SHA-256 Mozilla declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.
If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.
How the 100/100 score is calculated · why the source matters more than the reputation
Install Mozilla Firefox (en-US) with winget
Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.
Install
winget install --id Mozilla.Firefox --exactUpgrade later
winget upgrade --id Mozilla.FirefoxWhy --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.
Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.
Old versions of Mozilla Firefox (en-US)20 with hashes
The version history of Mozilla Firefox (en-US), each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

Common questions
- Where do I get the full Firefox installer?
- Mozilla publishes complete standalone installers alongside the stub. This page lists the exact URL from Mozilla's manifest with its SHA-256, so you get the full package rather than the downloader.
- Can I install Firefox without an internet connection?
- Yes, with the full installer. The default stub from the Mozilla download button needs a connection because it fetches the browser while installing.
