Best Browser Reviews

Mozilla Firefox has been around for a long time, and that means it’s gone through many iterations with varied success. In 2017, it launched its quantum update, which improved the speed and overhauled the design. This Firefox review will give you an idea of how it stacks up against other browsers.

Firefox is among the fastest browsers. It offers a lot of great features out of the box, as well as a solid library of add-ons and extensive customization options. Plus, it comes with strong privacy protection and, because Mozilla is a nonprofit organization, it has little incentive to collect and sell your data.

Firefox is available on most devices and operating systems, including Windows 7, 8, 8.1 and 10, macOS X 10.9 and later, Android Jelly Bean and later and iOS 11.0 and later. For this review, we used a laptop running Windows 10 and an iPhone on iOS 12.3.

Strengths & Weaknesses

Features

95% - Excellent

By default, Firefox sports a clean and simple interface that isn’t much different from other major browsers, such as Google Chrome. The tabs, address/search bar and bookmark bar are layered on top, and there’s a space for navigation controls on the left.

That said, unlike Chrome, Firefox comes with a lot of customization options for the interface. Every element of the basic UI can be moved around, and several buttons can be added anywhere you like with a simple drag-and-drop process.

Firefox was the first major browser to offer external add-ons, and though its library has since been eclipsed in size by Chrome’s, it still offers a wide variety of functionalities, such as tab groups, password managers, built-in notes and much more.

Setting up and syncing your browser across devices is quick and easy. As long as you create a Firefox account, your bookmarks, preferences, search history, logins, add-ons and even open tabs will be synced between your devices. Check out our guide on how to backup Firefox bookmarks to learn more about the process.

That said, Firefox warns that it’s not a backup service, so if you don’t sync more than one device, nothing will be saved if that device breaks or you uninstall the browser. Check out our list of best cloud backup services if you’re looking for a way to get around this.

That might sound like a limitation, but it means that Mozilla doesn’t keep giant records of its users’ synced data, which is great for privacy, especially compared to Chrome, where Google will collect any information about you it can.

On the right side of the address bar are small but useful features. By clicking the arrow pointing down, the address bar extends to show you the last 10 searches you made, as well as alternative search engines, such as Wikipedia, Amazon or Twitter. You can customize those additional search engines, too. Firefox gives you many options to make easily accessible.

Another fantastic feature is the screen capture tool. Located in the three-dots menu next to the address bar, it allows you to take a screengrab of an entire webpage without scrolling. You can also select specific parts of a page to screengrab, which saves you the effort of manually selecting and cropping when you only want to share part of a page.

Another handy sharing feature in the same menu is the “email link” option that automatically creates an email using your default email provider, which you can customize, to send the link. There’s also a button to copy the link, though that’s less useful, as well as an option to send the link to one of your other devices.

There’s a reader view, too, which strips articles of unrelated content and formats them into an easily digestible style, as well as providing you with an estimate of how long they’ll take to read. The built-in .pdf reader is also useful, but it lacks advanced features, such as document signing or support for dynamic .pdfs.

Firefox also comes with built-in support for Pocket, which is an application that lets you discover and save articles across devices.

Firefox Mobile Features

Firefox for mobile is a lot less feature heavy than the desktop version, but it still comes with handy tools. In the menu at the bottom right, you can disable all images, which is great for those with small data plans or slow connections, as well as enable or disable night mode and tracking protection.

By opening the menu next to the address bar, you can request the desktop version of any site, share or copy the URL and add the current page to your reading list, which gives you offline access to it. When you tap the search bar, the menu is replaced with a QR code scanner.

There’s also a version of the browser for iOS and Android called Firefox Focus. It’s designed to be minimal, comes with far fewer features and focuses on protecting privacy. That said, private mode in regular Firefox does the same job, so its main appeal is the stripped-down interface and minimalist approach to browsing.

Ease of Use

90% - Excellent

Firefox has a sleek and easy-to-understand interface that makes browsing a simple and comfortable experience. That said, though older web apps sometimes work better with Firefox than Chrome, the latter’s market dominance means that you’ll occasionally run into bugs and problems with modern web applications when using Firefox.

Ease of Use on Desktop

The desktop version of Firefox has a standard layout. Your search bar and bookmarks are placed on the top of the screen, with navigation controls to the left and menus located on the right. The drop-down displaying previous searches and alternative search engines is also useful if you need to use multiple search providers.

Tabs are clearly separated, and rather than minimizing them to the point of just being favicons, Firefox opts for a horizontal scrolling approach, leaving the tabs big enough that you can still read part of the title.

Ease of Use on Mobile

Firefox is just as easy to use on mobile. The address bar is at the top of the screen, with a button next to it for reader mode and the menu with options for sharing, bookmarking and requesting desktop websites.

The navigation controls and tab menu are at the bottom of the screen, and the tabs are displayed in two separate overviews of regular and private windows that you can switch between.

Performance

80% - Good

Firefox is one of the fastest major browsers, clocking in just behind Chrome on desktop and ahead of Microsoft Edge and Opera. On mobile, our tests showed it to be faster than Chrome and Safari, but not by a huge margin.

When it comes to system resources, Firefox has a high initial footprint, using large amounts of RAM when you only have a few tabs open. That said, the more tabs you have open the more efficient it is compared to its competitors, using significantly less RAM than Chrome once you have a lot of tabs open simultaneously.

Security

85% - Very Good

Firefox receives high marks on security, but as we concluded in our article on which web browser is the most secure, it doesn’t do quite as well as Chrome.

Firefox comes with a pop-up blocker as well as a block on known malicious websites using the Google safe browsing database. It also warns you when you visit a website using an unsecure HTTP connection, though the warning is harder to spot than it is in Chrome.

Another crucial aspect of software security is the frequency of updates, and Mozilla does well in that regard, too. Generally, if a security flaw is detected, it responds and releases a fix within a day. By default, the browser uses a background service to automatically check for and download updates, meaning you won’t inadvertently keep using an unsafe version.

Passwords stored locally can be protected with a master password, though this is turned off by default, so you have to manually add one to prevent your passwords from being available to anyone with physical access to your machine.

Privacy

100% - Excellent

Privacy is Firefox’s greatest strength. It comes with strict tracking controls that let you block trackers in all windows, and even customize what to block. For example, you can choose to block trackers and cryptominers but leave cookies enabled. In private mode, all those are blocked by default.

Firefox also has a great data collection policy. It collects data for development purposes, but that doesn’t include your browsing or search history and the data’s tied to a random numerical identifier rather than your name or user account. If that’s still too much for you, the browser lets you turn it off without affecting performance or functionality.

Because Mozilla is a nonprofit organization and its business isn’t predicated on the collection and sale of its users’ data, it’s far easier to trust it about its privacy measures. The company even releases an annual financial report explaining where its money comes from and how it’s spent.

Though Firefox does great with privacy, if you want to do more to ensure your anonymity, check out our anonymous browsing guide.

The Verdict

Firefox is a great browser, especially if you’re concerned with your privacy. Little information is collected about you by default, and even that can be turned off. You also get a strong private browsing mode with strict tracking and cookie protection.

The browser is easy to use, too, with great, small features, such as the screenshot tool and alternative search engines, packed into the browser. Plus, the large library of add-ons lets you add all sorts of features that the browser is missing.

The main issues with Firefox are occasional compatibility problems with newer web apps and high RAM usage during low load. Though those are real issues, the excellent privacy, design and features more than make up for them.

One thought on “Firefox”

  1. Firefox User Rating

    I have been using Firefox for more than a decade. About a year ago I noticed that, my computer gets crippled, if I use Firefox. I figured out that, Norton Anti Virus has something to do with it.
    Yesterday, I right-clicked on Firefox.exe file and selected “File Insight”. Norton showed “Fewer than five users in the Norton Community have used this file.” Are you kidding me?
    It seems to me that, Norton is deliberately doing this to Firefox.
