How can I get the latest version of Firefox on Windows XP or Vista?

Although Firefox will run on Windows XP Service Pack 2 (SP2) or above, the latest installers for Firefox require Windows XP with Service Pack 3 (SP3) or Windows Vista with update KB2763674. To work around this issue, a two-step process is necessary to install the latest version of Firefox on Windows XP SP2, Windows XP SP3 or on Windows Vista. Please follow these steps:

  1. Download and install Firefox up to version 43.0.1 (link to download).
  2. After installing this version you can use the Firefox updater to install the latest version of Firefox. See the article Update Firefox to the latest version for details.

We're sorry for the inconvenience.

For advanced users:

On Windows XP SP3 or up-to-date Vista operating systems, you can download the full installer for the latest version of Firefox from either one of these download sites:

For example, to download the Firefox 47.0.1 Windows English (US) full installer, navigate to /47.0.1/win32/en-US/ and choose the file Firefox Setup 47.0.1.exe.

Before downloading, read the System Requirements and see the Release Notes for information about the latest Firefox release.
