There are many reasons to update Firefox to the latest version. Most often, you might do this when the browser isn't working correctly. Another reason is that hundreds of bugs are fixed with each release, which prevents problems so you never have to experience them.

It's easy to update Firefox to the newest version. Here's how:

How Do I Update Firefox?

To force the newest update, download and install Firefox directly from Mozilla:

Depending on how you configured Firefox, updating may be automatic, meaning you don't need to manually download and install each update.

Check your update settings in Firefox from the menu bar at the top right. Go to Settings > General > Firefox Updates. In there is an option to always keep the browser updated.

What Is the Latest Version of Firefox?

The latest version of Firefox, v109.0, was released on January 17, 2023. Here's what's new:

  • Manifest Version 3 (MV3) extension support is now enabled by default (MV2 remains enabled/supported). This major update also ushers an exciting user interface change in the form of the new extensions button.
  • The Arbitrary Code Guard exploit protection has been enabled in the media playback utility processes, improving security for Windows users.
  • Colorways will no longer be in Firefox. Users will still be able to access saved and active Colorways from the Add-ons and themes menu option.
  • The Recently Closed section of Firefox View now equips users with the ability to manually close/remove url links from the list.

Mozilla's See What's New in Firefox 109.0 page provides the full list of changes and a link to what was new in the previous version.

Other Versions of Firefox

Firefox is available in many languages for Windows, Mac, and Linux, in both 32-bit and 64-bit. You can see all of these downloads on one page on Mozilla's site.

Not all operating systems are supported. Check Firefox System Requirements for all the details. The posted requirements for the latest Firefox version include Windows 11, Windows 10, Windows 8, Windows 7, macOS 12-10.12, and GNU/Linux.

Firefox is also available for Android devices from the Google Play store and for Apple devices from the iOS App Store:

Pre-release versions of Firefox are also available for download.

A number of download sites offer the latest version of Firefox, but some of these sites bundle additional, probably unwanted, software with their download of the browser. Save yourself the trouble and use Mozilla's website to download Firefox.
