Mozilla Firefox as a Linux alternative to Google Chrome

Updated October 18, 2026

Our verdict

Mozilla Firefox is a solid replacement for Google Chrome on Linux. It offers comparable speed, strong privacy defaults, and a mature extension ecosystem, making it suitable for everyday browsing, web development, and privacy‑conscious users. Power users who rely heavily on Chrome‑specific features like built‑in PDF viewer quirks or certain Chrome‑only extensions may need to adjust, but for most tasks Firefox works just as well.

Install Mozilla Firefox

What works the same

Both are Chromium‑derived browsers with modern HTML5 support
Cross‑platform availability (Linux, Windows, macOS)
Support for extensions/add‑ons
Regular security updates
Sync capabilities for bookmarks, passwords, and history

What is different

Firefox uses the Gecko engine instead of Blink, affecting some site rendering quirks
Built‑in tracking protection and stricter privacy defaults out of the box
Integrated Pocket reading list, not present in Chrome
Chrome’s native PDF viewer and built‑in Flash support (deprecated) differ from Firefox’s PDF handling
Chrome’s tighter integration with Google services (e.g., Google Translate, Docs) is absent in Firefox

Opening your Google Chrome files

Firefox can open any standard web page, bookmark file (HTML), or password export that Chrome produces. Importing Chrome bookmarks is straightforward via the browser’s import wizard. Exporting Firefox data to Chrome isn’t automated, but you can export bookmarks as HTML and import them into Chrome manually. Other proprietary Chrome data formats (e.g., Chrome’s sync data) have no direct equivalent, so manual migration is required.

Switching from Google Chrome to Mozilla Firefox, step by step

Install Firefox from your distribution’s package manager.
Launch Firefox and run the built‑in import wizard to pull Chrome bookmarks, history, and saved passwords.
Export Chrome bookmarks as an HTML file (chrome://bookmarks) and import them into Firefox if the wizard missed any.
Reinstall needed extensions from Firefox’s add‑on site.
Set Firefox as the default browser in your desktop environment.
Adjust privacy and UI settings to match your preferences.

Frequently asked questions

Will my Chrome extensions work in Firefox?

Only extensions that have been ported to Firefox’s WebExtension API will work; many popular ones are available, but some Chrome‑only extensions have no counterpart.

Can I sync my Chrome passwords to Firefox?

Firefox can import passwords saved in Chrome during the import process, but ongoing sync requires using Firefox Lockwise; there’s no live cross‑browser sync.

Is Firefox as fast as Chrome on Linux?

Performance is comparable for most sites; specific benchmarks may vary, but Firefox’s recent updates have closed the gap with Chrome’s speed.
