Overview
Firefox runs on its own engine rather than the one nearly everything else shares, and that independence is most of the argument for using it. Sites behave slightly differently, extensions have more capability than the restricted model elsewhere allows, and the interface can still be reshaped substantially through user styles and configuration flags for anyone who wants to.
The privacy stack is on by default and does not require a hunt through settings. Enhanced tracking protection blocks cross site trackers, cryptominers, fingerprinting scripts and social trackers, and total cookie protection keeps cookies in a separate jar per site so a tracker cannot follow a session from one domain to another. Container tabs go further by isolating whole browsing contexts, so a work account and a personal one can be logged in at the same time in the same window.
Day to day it does the ordinary things well. Tab groups and vertical tabs for people who keep too many open, a reader mode that strips a page down to the text, a picture in picture player that follows you between tabs, a built in screenshot tool that captures a full page rather than a viewport, a password store with a primary passphrase, and profile management for keeping entirely separate browsing setups on one machine.
What it does well
Independent engine
Its own rendering and scripting engine, which keeps the web from depending on a single implementation.
Tracking protection by default
Cross site trackers, fingerprinters, cryptominers and social trackers blocked without configuring anything.
Container tabs
Isolate browsing contexts so several accounts on the same site stay logged in side by side without conflicting.
Real extension capability
The extension model still permits content blockers and page modifying add-ons that a restricted model would prevent.
Practical built ins
Full page screenshots, reader mode, picture in picture, a password store with a primary passphrase, and separate profiles.

Installation
- Extract the archive and close any running browser instance.

Before you start
Strict tracking protection breaks a small number of sites, the shield icon disables it per site.
Profiles are self contained folders, copying one moves an entire setup to another machine.
This is the offline installer rather than the small stub, so it installs without a connection.
Questions about this title
Is this the full offline installer?
Yes, the complete package rather than a downloader stub.
Can I import from another browser?
Yes, bookmarks, history and stored passwords import on first run.
Do container tabs need an add-on?
The base isolation is built in, and an add-on adds the per-site container assignment interface.
Does it support enterprise deployment?
Yes, policy templates are included for configuring installs centrally.
About this listing
This entry was checked on a clean install of Windows 10 / 11 (32-bit and 64-bit) before it was published, and it is rechecked whenever the package is rebuilt. The figures on this page come from the site index rather than from the publisher, so the download count is what people here have actually pulled.
If a mirror stops answering, use the contact form and it gets replaced. Reports about a specific title are handled faster than general messages because they name the file, the mirror and the point at which the transfer stopped.
Requests for a different version, a different language build or an older release go on the requests page. Older versions of a title are usually still held even when only the current one is listed.
