System Requirements

Hardware Requirements

Pale Moon is designed to take advantage of hardware features any reasonably modern desktop computer should have. As such, it is built to use broadly-present CPU features, and works best with graphics cards that have good acceleration support.

Minimum requirements for official builds:
  • A processor with at least SSE2 support (any CPU that is not museum-grade should be fine).
  • We only support 32-bit on Windows. All other operating systems require 64-bit.
  • At least 2 GB of free RAM.
    While it may be possible to run it in limited fashion on less RAM, it isn't recommended as memory pressure will cause a lot of performance loss and may cause crashes.
  • A reasonable screen size (720p or higher).
Recommended:
  • A 64-bit processor and O.S.
  • 4 GB of free RAM.
  • A dedicated GPU with stable driver support.

Microsoft Windows

System requirements when running on Microsoft Windows:
  • Windows 7 with service pack 1 or later. We do not support Vista or Windows XP.
  • All applicable security updates installed.
  • At least 150 MB of free drive space for installation. More recommended for caching and profile data.

Linux

Pale Moon is specifically optimized for current-day processors and as such requires a reasonably modern system to run properly. See also hardware requirements above. Especially for Linux, often used on very old hardware, this is a point of note.

System requirements:

  • A modern Linux distribution. The browser may not work well on old or LTS releases of Linux.
  • 2GB of RAM (4GB or more recommended for heavy use).
  • GTK 2.24 or GTK 3.22+, depending on which version you download. GTK4 is not supported.
  • GLib 2.22 or higher
  • Pango 1.14 or higher
  • libstdc++ 4.6.1 or higher
NOTE: Linux 32 bit binaries have been discontinued. However, your distribution (or one of the fantastic package contributors) may still offer 32 bit packages at their discretion. If they do you should remove the "generic" binary and install said package. Otherwise, to continue using the Pale Moon binaries we distribute, please update to a 64 bit distribution of your O.S..

Apple Mac

An Intel 64-bit or Apple Silicon Mac running MacOS X 10.7 or later.

FreeBSD

Our support for FreeBSD will be for the Legacy, Production and Upcoming trees. i.e. if the Legacy branch is 12, then FreeBSD 12 or later is required and 11 or before is unsupported. When version 14 will be promoted to Production and 13 will become Legacy, as 15 will be created as the new Upcoming tree, we'll start building with a minimum of 13 and 12 or before will be out of support.

System requirements:
  • A 64-bit Intel machine and 64-bit FreeBSD.
  • GTK 2 or 3 package installed.
  • ALSA package installed.
