Firefox Fast & Private Browser

Blocking trackers and browsing privately

Tracker blocking runs automatically. The developer says Firefox stops social media trackers, cross-site cookies, crypto miners and fingerprinting scripts. Total Cookie Protection keeps each site's cookies confined to that site.

Private tabs do not save history, searches or cookies. They can be locked with the device's own security, so they stay closed until the phone is unlocked.

Passwords, tabs and syncing between devices

Firefox can generate new passwords, store them and autofill them into sign-in forms. Tabs can be organized and switched between, and tabs, bookmarks and passwords sync across devices so you can pick up where you left off.

Searches can go to a private search engine you choose, and you can switch engines from the search bar.

Reading, multitasking and page summaries

Reader View removes clutter from articles. Picture-in-picture keeps a video visible while you use other things on the phone.

Shaking the phone produces a summary of the key points on a long page. AI features can be turned off entirely, or switched on one feature at a time.

Customizing the browser and adding extensions

Extensions such as ad blockers can be added to the browser. You can move the search bar, change the home screen, layout and shortcuts, and adjust settings to match how you browse.
