Why switch

Why people are leaving Firefox

Trust is eroding

Terms-of-use changes, advertising ambitions and features like AI Recall have pushed long-time users to question Mozilla’s direction — and look for exits.

Tab workflows moved on

Power users built tree-style workflows Firefox never shipped natively. Modern rivals now include vertical tabs and workspaces by default.

AI is the new baseline

While rivals ship AI that summarizes, organizes and even acts on the web, Firefox’s AI story is still catching up.

Matched to you

Five Firefox alternatives, five kinds of switcher

There is no single “best” replacement — only the best one for your reason to switch. Find your profile below.

Brave

Best for privacy

Privacy first

Shields block trackers and ads by default, with optional Tor windows. If you left Firefox over trust, Brave is the cleanest privacy upgrade on Chromium.

Vivaldi

Best for tweakers

Power tabs & customization

Tab tiling, command chains and endless UI tuning. The spiritual successor for users who tweaked Firefox to its limits.

Tabbit

Best for AI work

AI-native workflow

An Agent that actually does the clicking — research, booking, form-filling — plus vertical tabs and workspaces. The modern replacement for Firefox-era workflows.

Zen

Closest to Firefox

Familiar Firefox feel

Open-source, Firefox-based, with a polished Arc-like sidebar. The gentlest switch if you still love Gecko.

Chrome / Edge

Best for sync

Full ecosystem sync

If your life runs on Google or Microsoft accounts, their browsers sync passwords, history and extensions across every device you own.

Our pick for AI work

Why Tabbit is the modern Firefox alternative

Firefox power users loved control and tab mastery. Tabbit keeps that spirit — and adds an AI Agent that finishes the work.

Agent Mode that does the work

Describe the outcome — “compare these hotels and fill the booking form” — and Tabbit’s Agent executes the steps in its own tab group while you keep working elsewhere.

Vertical tabs + workspaces, native

The tree-style workflows Firefox users loved, built in and synced — no extensions to install, break or maintain.

Your extensions come along

Chromium under the hood means the Chrome Web Store just works, so your switching cost stays near zero.

Free during public beta

Full access to top AI models and Agent Mode while in beta, on macOS and Windows.

Switch in minutes

How to move from Firefox in three steps

Export from Firefox

In Firefox settings, export bookmarks to HTML and passwords to CSV — it takes about a minute.

Import into Tabbit

Open Tabbit’s import wizard and pull in bookmarks, passwords and history from Firefox in one click.

Rebuild as workspaces

Turn your old tab groups into synced workspaces, pin your daily apps, and let the Agent handle the repetitive tasks.

FAQ

Firefox alternatives: common questions

What is the best alternative to Firefox in 2026?+

It depends on why you are leaving: Brave for privacy, Vivaldi for customization, Zen for a familiar Firefox feel, and Tabbit if you want an AI-native browser that keeps vertical tabs and adds an Agent that executes tasks for you.

Why are people switching away from Firefox?+

Common reasons include eroding trust in Mozilla’s decisions, controversial AI features, slower adoption of modern tab workflows, and the pull of Chromium’s much larger extension ecosystem.

Can I import my Firefox bookmarks and passwords?+

Yes. Every major alternative — Brave, Vivaldi, Zen and Tabbit — imports bookmarks, passwords and history directly from Firefox during setup, usually in one or two clicks.

Do Firefox alternatives support my extensions?+

Chromium-based options like Brave, Vivaldi and Tabbit run Chrome Web Store extensions, which cover most popular add-ons. Zen, being Firefox-based, uses Firefox’s own extension store.
