Good on resources

Battery-friendly video streaming: We tested video streaming on both Firefox and Chrome. While Chrome usually provides smoother page scrolling, Firefox surprisingly pulled ahead when it came to CPU power consumption with HD videos on YouTube, one of the most popular browsing activities. This power consumption has a direct effect on how long your battery lasts, and on the likelihood of a laptop fan noisily kicking in to keep your PC cool.

Easy reading thanks to smooth text scrolling: On a text-heavy Web page, Firefox does a better job than Google Chrome (Windows, Mac, Android, iOS) at making vertical scrolling scale to your Windows mouse settings. While the default scroll speed is relatively slow, Firefox has a lot more steps between "not enough" and "way too much." Text-heavy webpages also tend to glide up and down more smoothly in response to your mouse wheel movements, which makes it easier for your eye to track where you are on a page. However, Chrome still scrolls more smoothly on media-heavy pages.

Highly customizable interface navigation: Mozilla introduced a UI overhaul in November 2013 that didn't go over very well. Among other things, the standard menu design was replaced with a "hamburger" button that opened to reveal a number of icons. On the bright side, Mozilla gives developers deep access into modifying Firefox's behavior, and one of them quickly introduced Classic Theme Restorer, which ended up giving Firefox the most user-customizable interface of any browser on the market, even three years later. With Classic Theme Restorer, the bookmarks button doesn't have to look (confusingly) like a clipboard; you can tell at a glance which custom search engine you have loaded; and you can freely mix design elements from both the "classic" UI and the overhaul.

Underwhelming performance on media-heavy Web pages: Embedded videos, animated images, and large static images have become a very popular way for both advertisers and content creators to reach their audiences. But this rich-media environment takes its toll on a Web browser that can't load all that data smoothly. Chrome feels prepared for this evolution, while Firefox arguably requires an ad blocker to prevent chunky scrolling and delayed loading of different sections on the page. (Firefox on Android fares much better in this department.) Basically, Chrome feels optimized for visual elements, while Firefox feels optimized for reading.

Mozilla has committed to finally replacing the Gecko page rendering engine with a new one called Quantum, but the company doesn't expect to make it available until the end of 2017.

Sync requires managing another account: With Google Chrome, you can log in to your Google account (which you already have if you use Gmail or subscribe to YouTube channels), and it will pull in your bookmarks, add-ons, and themes from any other device where you've used the Chrome browser with that Google account. With Firefox, you need to create a separate Firefox account, which you won't use anywhere else. Thankfully, though, the login screen works just fine with password managers like LastPass (Chrome desktop, Firefox desktop, iOS, Android).

Nothing truly revolutionary

Mozilla Firefox is a popular Web browser available on a variety of platforms. Its code DNA reaches back to the dawn of the World Wide Web and has shaped other software and software companies, including The Tor Project (Windows, Android, Mac), the Opera browser (Windows, Android Mac) Adobe Acrobat (Windows, Android, Mac, iOS) Oracle, and Logitech.

The first thing you’ll notice when you open Firefox is just how fast and attractive it is. The purple and orange color scheme has really been polished up and all the menus and options look clean, minimalist, and easy to navigate. Firefox’s speed, which is one of the major selling points, also pleases. It’s all very well for Firefox and testers to tell us, precisely, how fast it is (and they do), but it looks and feels fast when you’re using it, which is arguably the most important point.

Connected to this, Firefox also uses less memory and, together, they have an impressive effect on resource-hungry tasks, like playing games or running other programs on your computer. Firefox also makes special mention of tabs, saying that they’ve changed the way the browser deals with tab processes to unlink them, which makes them faster, more agile, and less likely to crash or hang.

For most people who look to Firefox, the privacy gains are the main event – especially if you’re looking to make a change from Chrome. When it comes to ad blockers, Firefox has some heavy-duty weapons under the hood. You choose the level of protection you need from the browser, picking from highly-configurable Standard, Strict, and Custom modes, and there are also a number of Firefox-approved ad-blocking extensions you can add to up the level of protection.

You’ll also be able to exercise plenty of control over Firefox privacy by delving into the settings options – in both the Privacy Protections and Options menus. Here you can tweak the ad blockers, as we mentioned, as well as changing permissions for things like the camera, allowing or preventing Firefox from collecting data, and deciding when and how you deal with dangerous downloads and security certificates. There’s also a super-charged, tracker blocking private mode and a default password manager (although you can get more sophisticated password managers as separate downloads or add-ons).
