Finding a secure and fast web browser is not an easy task, right? It’s also easier than ever, thanks to the new version of Firefox Browser from Mozilla.

Almost anybody can use Firefox for Windows, all you need is a PC or laptop and an internet connection.

It is free and supports 64 bit and 32 bit systems. So, even if you’re a new internet user, you won’t have to waste a lot of time comparing available web browsers and choosing the right one for you.

In this article, I’m going to discuss how to download and install Firefox Browser on your device. In addition, we will highlight the main features of the latest version update.

Ready? Let’s start!

Firefox, the fiery orange fox gracing your screens, represents far more than just a web browser.

Developed by the non-profit Mozilla Foundation, it champions privacy, security, and open-source innovation.

This guide explores the world of Firefox, equipping you with the knowledge to download, install, customize, and leverage its full potential.

64-bit and arm64 Versions

Modern computers often utilize 64-bit architecture for improved performance. Firefox offers a 64-bit version that leverages this power for faster browsing and smoother handling of complex webpages.

How to Download & Install

Preparation:

System Requirements: Head to the Mozilla website (https://support.mozilla.org/en-US/kb/supported-platforms-and-system-requirements) to ensure your Windows system meets the minimum requirements for smooth operation.
Download Option: Choose between two methods:

- Online Installer: Visit the official download page (https://www.mozilla.org/en-US/firefox/windows/) and click the big orange “Download Now” button. This option automatically detects your Windows version and downloads the most suitable installer.
- Offline Installer: Prefer to be prepared? Download the offline installer from the same page by clicking the small down arrow next to the “Download Now” button and selecting “Windows Offline Installer.” This allows installation even without an internet connection.

Downloading:

Once you click “Download Now,” the installer file (usually named “Firefox Setup.exe”) will begin downloading. The download time depends on your internet speed.

Installation:

Installing Firefox 1

Locate the downloaded file: After download completion, navigate to your downloads folder (usually “Downloads”) using File Explorer.
Run the installer: Double-click the downloaded “Firefox Setup.exe” file.
User Account Control (UAC) Prompt (Windows Vista and Later): You might see a prompt asking for permission to make changes to your computer. Click “Yes” to proceed.
Installation Wizard: The Firefox Setup Wizard will appear. Here’s a breakdown of the options:

- Default Browser: Check the box if you want Firefox to become your default web browser. This means any web links you click will open in Firefox.
- Installation Folder: By default, Firefox installs in “C:\Program Files\Mozilla Firefox.” You can change this location by clicking “Browse” and selecting a different folder. (Not recommended for most users).
- Shortcut Creation: The wizard will create shortcuts for Firefox on your Start Menu and Desktop by default. You can uncheck these options if you don’t want them.

Click “Install”: The installation process will begin. A progress bar will indicate the completion status.
Finish: Once the installation is complete, you’ll see a “Finish” button. Click it to launch Firefox.

Installing Firefox 2

Congratulations! You’ve successfully downloaded and installed Firefox on your Windows PC. Now, you can start exploring the web with a privacy-focused and customizable browser.

Uninstalling Firefox: When It’s Time to Move On

If Firefox no longer suits your needs, uninstalling it is a breeze. The process differs slightly depending on your operating system.

Generally, you can find Firefox in your Control Panel (Windows), Applications folder (Mac), or through package management tools (Linux). Locate Firefox, initiate the uninstall process, and follow the prompts.

FAQ

Does Firefox still work on Windows 7, Windows 8.1 and Windows 10?

Windows 10 and Windows 11 are supported. Mozilla ended security updates for Windows 7, 8 and 8.1 in early 2026, so those systems no longer get safe, current Firefox builds. Upgrade the operating system instead of relying on an old browser, and check Mozilla’s system requirements page for the latest details.

Which Firefox download should I choose: 64-bit, 32-bit, ARM64 or the offline installer?

Choose 64-bit for most Windows 11 and Windows 10 PCs. Pick 32-bit only on a 32-bit system and ARM64 only on Windows devices with an ARM processor. The offline installer contains everything, which helps on slow connections or when you set up several computers.

Does uBlock Origin still work in Firefox, and is it better than Chrome for ad blocking?

Firefox still supports the older extension format the full version of uBlock Origin relies on, and Mozilla has said it has no current plans to remove it. Chrome has moved to the newer format, which limits classic ad blockers. Policies can change, so check Mozilla’s add-ons site before relying on a specific extension.

How do I import bookmarks and passwords from Chrome or Edge into Firefox?

Open the Bookmarks menu, choose Manage bookmarks, then Import and Backup, and select Import data from another browser. For passwords, type about:logins in the address bar, open the three dot menu and choose Import from another browser. Close the other browser first.

How do I make Firefox my default browser on Windows 11?

Open Firefox, go to Settings, then General, and click Make Default. If Windows does not apply it, open Windows Settings, then Apps, then Default apps, choose Firefox and set it for HTTP, HTTPS and HTML. Windows 11 stores these choices per file type.

Why is Firefox slow or using too much memory, and how do I fix it?

Open about:processes to find the tab or extension using the most resources and close or remove it. Then restart in Troubleshoot Mode from the Help menu to test without extensions. If problems continue, update your graphics driver or use Refresh Firefox from the about:support page, which keeps bookmarks and passwords.
