Firefox Alternatives (2026): 10 Browsers Grouped by Type

If you're reading this, you're probably a Firefox user with a reason to look around: an older computer that's been left behind, a wish for stricter privacy defaults, or curiosity about browsers built around workspaces and tab groups. Below are ten options, grouped by what they're built for rather than ranked, because the right pick depends entirely on why you're leaving and what you'd miss.

Some of these aren't a clean break

Here's the part most round-ups skip. Several of these browsers sit very close to the one you're leaving. LibreWolf calls itself a custom, independent version of Firefox. Mullvad Browser came out of the Tor Project, made at Mullvad's request. So switching can mean staying on a similar engine with different settings, which is great if you like how things work today and only want a stricter posture, and much less useful if you were hoping for something new.

What you'd be giving up

Start with what you already have. Out of the box, your current browser stops trackers automatically, by its own account, and asks you to set nothing up. Hold every name below to that standard on day one: anything that falls short means a first week of add-ons and toggles just to get back level. That applies whichever group a browser sits in, and it's why the privacy-first group is so busy.

Some people have no choice but to look. Firefox no longer supports Windows 8.1 and below or macOS 10.14 and below, and it points anyone on those systems to the extended support release, known as ESR. If that's you, try ESR before you rebuild your bookmarks somewhere else, because it may solve the problem without changing browser at all.

It's also worth thinking about updates. A browser is one of the most exposed pieces of software on any computer, so whichever you move to should be one you're comfortable keeping current. If a project looks quiet, or you can't tell who maintains it, treat that as a warning sign rather than a charming quirk.

Privacy-hardened builds

These suit people whose main complaint is being followed around the web. LibreWolf aims at privacy, security and user freedom, and Tor Browser is built for browsing without compromising privacy or anonymity. Brave's headline is blocking third-party ads on every website. Expect a plainer experience and the occasional site that doesn't behave until you relax a setting. That trade-off is the whole point of this group, and if it sounds annoying, skip ahead to the next one.

Brave

Best for: people whose main irritation is ads.

LibreWolf

Best for: a familiar feel, with uBlock Origin as its content blocker.

Mullvad Browser

Best for: privacy with Tor Project heritage.

Tor Browser

Best for: anonymity on desktop and Android.

Browsers for tab and workspace power users

If your complaint is clutter rather than tracking, look here. Opera keeps groups of tabs apart in what it calls Tab Islands, while Zen leans on workspaces, a compact layout and side-by-side views. Both put tab organisation front and centre, which matters if you routinely have forty things open across three projects and lose the one you need. They're the group most likely to change how your working day feels, for better or worse, so give them a full week rather than an afternoon.

Opera

Best for: keeping separate projects in separate tab groups.

Zen Browser

Best for: Workspaces, Compact Mode, Glance and Split View in one window.

Independent makers and open code

This last group is more about stance than a single feature: code anyone can read, a company that isn't one of the giants, or the same name on every device you own. Chromium is the open-source project whose code anyone can browse and build. Waterfox describes itself as free and open source, focused on privacy and customisation. Vivaldi describes itself as an independent European company that puts people first, with no tracking. If you're leaving because of who makes your browser rather than what it does, start here, and read each maker's own description of itself before you decide.

Chromium

Best for: tinkerers who want to read or build the source.

DuckDuckGo Browser

Best for: one name on Windows, Mac, Android and iOS.

Vivaldi

Best for: anyone who'd rather use a smaller, independent maker.

Waterfox

Best for: a free, open-source mix of privacy and customisation.

Which group should you start with?

If you're unsure, think about the last time your browser annoyed you. If it was a creepy ad that followed you from one shop to another, or a news site that crawled because of all the scripts loading in the background, start with the privacy group. If it was losing a tab you needed, or drowning in forty open pages, start with the workspace group. If it was something less tangible, a feeling that you'd like to know who's behind the software you use all day, start with the independent group.

Whatever you choose, keep your expectations sensible for the first week. Muscle memory is strong, and every browser puts its menus, shortcuts and settings in slightly different places. The first few days will feel slower even if nothing is slower, so judge it at the end of the week rather than the end of the first morning. If it still feels like a downgrade after seven days of real use, move on to the next candidate without guilt.

The awkward bits are usually small ones: saved form entries, site permissions such as which pages may use your camera, and the odd web app that only behaves in one browser. None of these is a reason to stay put, but list them before you start, so a missing permission on a video call doesn't catch you out in front of a client.

Before you switch: a checklist that saves a headache

Changing browser is easy to start and annoying to finish. Here's the order I'd do it in.

1. Check your operating system first, and try ESR if it's old.
2. Pick one group and only trial browsers from it.
3. List the add-ons you can't live without, such as a translation add-on or a screenshot tool.
4. Export bookmarks and passwords before you uninstall anything.
5. Run two candidates side by side for a normal working week.
6. Change your default only once one stops feeling strange.

Keep the old browser installed for a month afterwards. You'll be surprised how often a single site, a saved login or a half-remembered bookmark sends you back to look something up.

Frequently asked questions

Which of these is still in beta?

Zen Browser. Its own page says a Beta is now available, so treat it as pre-release software and keep another browser ready.

Is Vivaldi open source?

Not in its headline. Vivaldi leads with independence and a no-tracking promise, so look for the licence on its site before you assume either way.

Does DuckDuckGo make a Linux version?

Its desktop browser is listed for Windows and Mac only, so Linux users should look at the other names here.

Can I contribute to one of these projects?

Yes, if you write code. Chromium welcomes outside contributors to the project.

Will my Firefox add-ons work elsewhere?

Look up each one you rely on in the new browser's own add-on store before you switch, and treat a missing favourite as a reason to try another name on this list.

Which of these runs on Android?

Tor Browser is available for desktop and Android, and DuckDuckGo makes versions for Android and iOS alongside its Windows and Mac browser.
