Billed as the "privacy browser," Firefox Focus for Android is a secured version of Mozilla's popular browser with its Private Browsing function always on.


Really, really, really focused on privacy: Focus is a stripped-down version of the mobile version of Firefox, designed to keep your data secure and you private while you browse.

Blocks trackers: By default, the browser blocks ad trackers that can follow you across sites. It also automatically blocks analytic and social trackers that capture your browsing and social behaviors. You can also choose to have the browser not download web fonts for a page, which may speed up browsing but also may create odd-looking pages.

Pick your search engine: You can set your default search engine easily from the settings window. By default, Firefox uses Google, but you can switch to Bing, Amazon, or other search tools.

Add website shortcuts to your home screen: For easy access to websites, you can choose Add to Home screen from the settings menu.

Quickly erase your history: A notification dot on the app icon reminds you to erase your browsing history, including passwords.


It's not your full-featured Firefox: If you like finding a balance between convenience and security, this might not be the browser for you. Focus doesn't handle multiple tabs. (You can open a new one in the browser but can't have more than one open at a time.) You can't use Firefox extensions (although they are being considered). Focus doesn't sync with other Firefox browsers.

Bottom Line

Designed to keep you safe online, Firefox Focus steers clear of a lot of the niceties that you may expect in a browser but that may also put your data at risk. Instead, its focus is on giving you a secure window to the web.

Developer's Description

Browse like no one's watching. The new Firefox Focus automatically blocks a wide range of online trackers -- from the moment you launch it to the second you leave it. Easily erase your history, passwords and cookies, so you won't get followed by things like unwanted ads.

"Private browsing" on most browsers isn't comprehensive or easy to use. Focus is next-level privacy that's free, always on and always on your side -- because it's backed by Mozilla, the non-profit that fights for your rights on the Web.


- Blocks a wide range of common Web trackers without any settings to set

- Easily erases your history -- no passwords, no cookies, no trackers


- By removing trackers and ads, Web pages may require less data and load faster


- We believe everyone should have control over their lives online. That's what we've been fighting for since 1998.
