Firefox APK v159.0.1 (Private Browser) Latest Download

Download Firefox APK for Android. Firefox brings tracking protection, private tabs, extensions, and optional device sync into a mobile browser you can use for everyday searching and reading. Open websites, keep useful pages in bookmarks, and choose how you organize the tabs you want to return to.

The Android app is useful when you want browsing controls that extend beyond a simple address bar. You can review the trackers blocked on a page, add compatible extensions, or continue with tabs from another device through your Mozilla account.

Built-In Tracking Protection

Enhanced Tracking Protection is enabled by default. Firefox uses it to identify and block known trackers on the websites you visit. The protection panel in the address bar shows what is happening on the current page, giving you a way to inspect the feature rather than simply rely on a general privacy label.

You can choose Standard, Strict, or Custom protection in the settings. Standard provides the default balance, while Strict blocks additional tracking content and may affect some website functions. Total Cookie Protection also separates tracking cookies by the site that created them, helping limit cross-site tracking.

Private Tabs for Separate Browsing Sessions

Private tabs keep a browsing session separate from your regular tabs. They are useful when you want to look something up without adding those visited pages to your normal browsing history. Close the private tabs when you finish that session.

The tab tray keeps regular and private browsing in separate areas, so it is easier to see which mode you are using before opening another page. You can switch back to your everyday tabs without closing the work you already had open there.

Add Compatible Firefox Extensions

Firefox for Android supports compatible browser extensions, giving you more control over how websites behave. Depending on the extension you choose, you can add content blocking, change parts of the reading experience, or bring in another useful browsing tool.

Open the Extensions area to browse available options and read what an extension does before adding it. Firefox shows the access it requests during installation. You can later manage its settings, disable it, or remove it from the same area. Availability on desktop does not automatically mean an extension supports Android, so use the Android-compatible selection.

Organize Tabs, Groups, and Collections

The tab tray helps you move between open websites without losing your place in the current browsing session. This is useful when you are comparing several products, following links while researching a topic, or keeping a reference page open while you read another site.

Tab groups organize related open tabs together. Collections provide another way to save groups of websites you want to revisit later. Keeping a small set of related pages together is easier to navigate than leaving every search result in one long, unstructured list.

Firefox also provides tab settings for the layout and automatic closing behavior. Choose an arrangement that is easy to scan on your screen, and review old tabs occasionally so the pages you still need remain easy to find.

Sync Bookmarks, Passwords, and Open Tabs

Sign in to a Mozilla account when you want to connect Firefox across your phone, tablet, and computer. Sync can share selected browsing data such as bookmarks, history, saved logins, and open tabs between those installations.

You choose the categories to sync in the account settings. For example, you can keep bookmarks available on both your phone and computer and use the synced-tabs area to open a page that was left on another device. Basic browsing does not require connecting an account; Sync is an additional feature you can use when it fits your workflow.

Search, Save Pages, and Manage Downloads

Use the address bar to enter a website or start a search, then bookmark pages you expect to use again. This is useful for recurring reference material, a frequently visited account page, or a collection of resources you do not want to search for every time.

The downloads area gives you a place to find files saved through the browser. After a download finishes, open the file with a suitable Android app. For local videos and music, VLC for Android provides a separate media player with subtitle and playlist controls.

Choose a Universal or ARM64 APK

The universal APK contains support for the processor architectures included in that build. The ARM64 option is a smaller package for compatible 64-bit ARM phones and tablets. Both download choices provide the same Firefox release; the difference is the included processor support and resulting file size.

Choose the universal package when you need the broader architecture option, or ARM64 when you know it matches your device. The universal mirror provides an alternative download route for that same package. Your device must also meet the Android requirement shown in the app information.

Choose the Firefox APK that matches your device, using the mirror if you need another route for the universal package. After installation, open the browser and set up the privacy, extension, and optional sync features you want to use.
