Users on 64-bit Windows who download Firefox can get our 64-bit version by default. That means you get a more secure version of Firefox, one that also crashes a whole lot less. How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more.

What’s the difference between 32-bit and 64-bit?

Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit.

How do you get 64-bit Firefox?

If you’re running 64-bit Windows (here’s how to check), your Firefox may already be 64-bit. Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number:

• If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.
• If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more). You can still manually install 64-bit Firefox, if you choose.

If you need to run 32-bit Firefox or manually install 64-bit Firefox, you can simply download and re-run the Windows (32-bit or 64-bit) Firefox installer from the Firefox platforms and languages download page.

Mozilla Firefox for PC Windows

User rating User Rating

Mozilla Firefox is one of the most prominent browsers for Windows desktops and laptops. While it comes with plenty of features, Mozilla Foundation hasn’t compromised on faster browsing and privacy controls. With this versatile browser, you can indulge in casual surfing on the internet as well as intensive research. Compared to previous beta versions, Mozilla Firefox for Windows 10 is a faster and better tool. Since it has a clean interface, you can easily locate various features, including downloads, add-ons & extensions, bookmarks, and history

Plenty of features for endless browsing!

For many years, Mozilla Firefox lagged behind leading browsers in the industry. Some of the popular choices include Opera and Microsoft Edge. In 2017, Mozilla introduced Quantum, an excellent update that provided the company with a new lease of life. This update improved the browser’s speed and privacy, while making it lightweight on system resources.

While Mozilla isn’t known for a wide range of extensions, it introduced the popular Facebook container extension, which lets you place Facebook share and like buttons directly into the container. In case you’re concerned about Facebook using your data, you can disable this feature within a couple of clicks.

Is it a lightweight browser?

Compared to the previous versions, the latest installment of Mozilla Firefox is twice as fast. According to several speed tests, it takes less than 5 seconds to run the Firefox browser. Navigation and page load speed are also quicker, and allow you to seamlessly browse the internet.

While using Firefox, you can browse heavy video websites without any issues. Most importantly, the latest version of the browser consumes approximately 30% less memory than competitors. As such, it doesn’t slow down system processes, and lets you browse single or multiple tabs without disruptions or lags.

Does Firefox have anti-tracking features?

While browsers like Brave are known for privacy controls, Mozilla Firefox isn’t far behind. The platform comes with a wide range of anti-tracking features, which help secure your browsing experience. Moreover, these features ensure a faster browsing experience, considering there’s no need for heavy data requirements to track usage.

Since the browser comes with improved protection for trackers on Windows PCs, it not only speeds up your browsing experience but protects your machine from hackers and malicious websites. Once you start using Mozilla Firefox, you don’t need to worry about viruses and online threats.

The best part is that Firefox comes with customizable anti-tracking features. Therefore, it’s easy to manage the level of blocking required for your system. While the default setting blocks all tracking, you can choose to block certain websites for a personalized experience.

Like most browsers, Mozilla Firefox allows you to block third-party cookies. This feature can be easily accessed from the ‘Settings’ menu. Additionally, you can access it from the ‘Shield’ icon in the browser’s ‘URL’ bar. Just in case you’re not too tech-savvy, the tracking protection feature blocks all third-party cookies on default.

Comprehensive password manager

While browsing the internet, you tend to visit a wide range of websites. More often than not, each one asks for a login password. If you don’t remember passwords, it can be a tedious task to change them every now and then. Mozilla has extended the ‘Lockbox Password Manager’ previously used on iOS and Android apps, to Windows and Mac. It’s perhaps one of the most useful Firefox privacy controls. For desktops and laptops, the feature is called ‘Lockwise’. While Firefox isn’t known for an abundance of extensions, this one is quite useful.

Lockwise can automatically and securely save your passwords in the platform. As such, you can conveniently log in across devices. The feature saves you from the trouble of remembering every password and logging in individually on each website. Additionally, Mozilla Firefox comes with ‘Firefox Monitor’, which allows you to check email addresses that could be involved in a data breach.

With Firefox Monitor, you get detailed information about a wide range of email addresses being constantly monitored for breaches. In recent times, hackers have been targeting sensitive data of users around the world. With Mozilla Firefox’s improved tracking protection and other security features, you get a safer and secure browsing experience.

Does Firefox have customization options?

Customization is one of the best features of the latest Mozilla Firefox browser. With a simple right click on the navigation toolbar, you can easily customize individual components. Additionally, the UI makes it easier to drag and drop items. There’s also a built-in Add-ons Manager, which lets you discover, explore, and install Firefox add-ons within the browser. You can even check descriptions, recommendations, and ratings.

With thousands of customizable themes, Mozilla Firefox allows you to personalize the entire browsing experience. With the developer edition, webmasters can easily create advanced applications and content modules with Mozilla’s open-source platform and APIs.

An excellent choice for fast and secure browsing!

While Mozilla Firefox isn’t as popular as Google Chrome or Internet Explorer, it’s an excellent choice for faster surfing. With a wide range of security and browsing features, it provides you with cross-platform synchronization. Since it’s free to download, it’s a worthy candidate for surfing the internet. The most prominent benefits of using Mozilla Firefox include speed, flexibility, reliability, security, and customization options. Over the years, the company has set the bar high for other web browsers.

Without a doubt, Mozilla Firefox, is a lightweight, fast, and easy-to-use browser. While it was launched more than a decade ago and couldn’t get instantly popular, it is now counted among the leading browsers available online. Whether you use a 32-bit Windows machine or a 64-bit Windows system, Firefox will be an excellent choice. Since it’s available for multiple operating systems, you can continue using the browser across devices. All your data is synchronized in real-time.
