No shady privacy policies or back doors for advertisers. Just a lightning fast browser that doesn’t sell you out.

New in 81.0:
• You can pause and play audio or video in Firefox right from your keyboard or headset, giving you easy access to control your media when in another Firefox tab, another program, or even when your computer is locked.
• In addition to our default, dark and light themes, with this release, Firefox introduces the Alpenglow theme: a colorful appearance for buttons, menus, and windows. You can update your Firefox themes under settings or preferences.
• For our users in the US and Canada, Firefox can now save, manage, and auto-fill credit card information for you, making shopping on Firefox ever more convenient. To ensure the smoothest experience, this will be rolling out to users gradually.
• Firefox supports AcroForm, which will soon allow you to fill in, print, and save supported PDF forms and the PDF viewer also has a new fresh look.
• Our users in Austria, Belgium and Switzerland using the German version of Firefox will now see Pocket recommendations in their new tab featuring some of the best stories on the web. If you don’t see them, you can turn on Pocket articles in your new tab by following these steps. In addition to Firefox’s new tab, Pocket is also available as an app on iOS and Android.

Get it all on every device, without feeling trapped in a single operating system.

Better bookmarks:
Don’t agonize, lovers of bookmarking. Organize with Firefox.

• File that bookmark.
Get your faves all sorted with the bookmark star icon, which lets you add custom names and folders quickly. Then dial in your bookmarks toolbar to make sure you never lose sight of the links you love.

• Fly with that bookmark.
Take your favorites on the fly. Use Firefox Sync to access your bookmarks across all your devices, from desktop to mobile. Or try Pocket to save any online article, or page and come back to later – even without internet.

• Futz with that bookmark.
Practice your exactitude with every bookmark manager add-on you can think of, from full page snapshots to quick-switch sidebars to locked-down-tight private bookmarks.

More powerful private browsing.
More protection. Less worry. We’re obsessed with protecting your privacy. That’s why we’ve made Firefox Private Browsing more powerful than the others.

• Browse without a trace.
Sharing is caring, but that should be your call. Firefox Private Browsing automatically erases your online info like passwords, cookies and history from your computer. So that when you close out, you leave no trace.

• Catch those hidden trackers.
Some websites and ads attach hidden trackers that collect your browsing info long after you’ve left. Only Firefox Private Browsing has tracking protection to block them automatically.

• Shake off tracking weight.
Not only do trackers collect info, they can weigh down your browsing speeds. Only Firefox Private Browsing blocks ads with hidden trackers, so you can drop the baggage and browse freely.

Ad-tracker blocking:
The ad blocker – a secret weapon against annoying ads. So many ads, so little patience… It’s time to stop the madness. Choose from multiple ad-blockers approved for use with Firefox.

Create a tracker-free zone with Content Blocking:
On Firefox, you can use Privacy or Content Blocking settings to get even more control over ad trackers that serve you the ads. DNS over HTTPS (DoH) helps keep internet service providers from selling your data.

• Choose your level of protection.
Go easy with Standard mode. Get tough with Strict mode. Or do-it-yourself Custom mode.

• Cover your trail, block trackers.
Click on the Trackers box and you’ll be able to block trackers in two ways. One way to block trackers is to do it when you’re working in a Private Window. Another way to do it is to block trackers in all windows. Keep in mind that if you choose to always block trackers, some pages might not load correctly.

• Take a bite out of cookies.
Cookies are sent by websites you visit. They live on your computer and monitor what you’ve been doing on a site. When an airline hikes your rates because you’ve looked at plane tickets once that day, that is the handiwork of a cookie.

• Send a Do Not Track signal.
If you don’t want your online behavior used for ads, you can send websites a polite “thanks but no thanks” letter by checking the Do Not Track option of Firefox. Participation is voluntary, but the websites that participate will stop tracking you immediately.

• Speed up thanks to ad blockers.
In some cases, an ad blocker can help your browser go faster. When an ad is loading, it can slow down a website. At the same time, it takes longer to find what you’re looking for if you’re too busy closing yet another ad.

Balanced Memory Usage:
If your web browser uses too much memory, switch to Firefox.

• Speed up your computer.
Every computer program you run takes up some memory. When too much is used, your system can slooooowww down. Firefox aims for a balance — using enough memory to let you browse smoothly and leaving plenty of memory to keep your computer responsive.

• Browse faster, privately.
Explore the web faster with Firefox Private Browsing. Only Firefox’s private mode includes tracking protection which blocks ads with trackers from loading on pages. Decluttering sites means web pages can load faster.

Browser Faster:
Firefox is now faster and leaner

• Use less memory.
No one likes a computer hog! Firefox is a lean, mean (actually we’re pretty nice) browsing machine. Since we use less RAM than Chrome, your other programs can keep running at top speed.

• Get all the tabs without lags.
Multi-tasking with multiple tabs just got easier. Firefox is now a multi-process browser, which means that your tabs stay fresh and won’t take forever to reload. With 86% less hang time, switch quickly between tabs even as you open more.

• Level-up browser gameplay.
We led the tech to run 3D games at near-native speeds, and now Firefox is bringing better performance to online gaming. Our powerful browser reduces lags, speeds up ping times and optimizes overall gameplay through faster, leaner browsing.
