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.

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. The Firefox System Requirements page states that you must be running at least Windows 10 or macOS 10.15. That page details the requirements for GNU/Linux as well.

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.
